Compared with slope surface measurement, subsurface monitoring has the potential to detect abnormal changes at an earlier stage. Due to the large-scale deformation of landslides and the complex geological environment, the existing subsurface devices generally have limited measuring range or high economic cost. Thus, it is urgent to develop an advanced method to improve the sustainable monitoring of large subsurface deformation. In this study, a novel flexible device is designed for slope subsurface monitoring, which combines an active waveguide of acoustic emission and the distinctive structure of a large-deformation bolt. An experimental system is built and a loading process of three-stage deformation is carried out to test the performance of the flexible device. The kinematic, mechanical and acoustic emission parameters are synchronously obtained in the whole landslide model test. The results indicate that different evolution stages of a landslide can be distinguished by sliding acceleration. The axial tension within the anchor cable changes consistently with sliding thrust. In addition, using acoustic emission to quantify slope deformation has achieved strong correlation. An extra experiment with constant velocity is conducted to explore the precision of deformation quantification by acoustic emission. A schematic diagram is presented for how this novel device would be used for landslide monitoring in the field, with the potential practicability of stabilizing the slope.

Fractures and micropores have varying contributions to the gas permeability of fractured reservoirs. The quantification of the contribution of fractures and micropores that form a dual-porosity system for gas permeability is critical when attempting to accurately evaluate gas production. However, due to insufficient knowledge of fracture–matrix flow partitioning in such dual-porosity systems, it is challenging for previous models to quantitatively characterize the fracture heterogeneity and accurately evaluate the gas flow and permeability in fractured rocks. In this study, we propose a dual-porosity percolation model to quantitatively investigate the contributions of fractures and matrix micropores towards the gas permeability of fractured rocks. Using percolation theory, we establish fracture networks with complex heterogeneity, which are characterized by various fracture densities and percolation probabilities within a porous matrix with various fracture/matrix permeability ratios. The compressible Navier–Stokes and Brinkman equations were adopted to describe the gas flow in the fractures and porous matrix, respectively. The simulation results indicate that the gas permeability of the dual-porosity system has an exponential relationship with the fracture density and matrix permeability. The contribution of fractures and matrix micropores toward gas permeability can be classified by establishing a two-dimensional partitioning of the fracture–matrix flow related to the fracture heterogeneity and fracture/matrix permeability ratio. The contribution of matrix micropores cannot be neglected if the fracture density is lower than a critical value.

Acoustic emission (AE) monitoring has become an optional technology to quantify slope deformation. However, there are still challenges in developing generic AE interpretation strategies. Dynamics and kinematics models are two physical methods for analysing slope stability, which appear to improve the interpretability of AE monitoring data. The aim of this study is to explore the change patterns and interrelations of dynamics, kinematics, and AE measurements using a model test and physical analysis, to further understand the development process of a progressive landslide. A model test is designed based on the kinematics model of landslide three-stage deformation. An equation between factor of safety (FoS) and thrust is proposed based on the mechanical model of a landslide test. There is a clear correspondence between the displacement and inverse velocity during the deformation-controlled process. Relationships are uncovered between the thrust and FoS as well as the thrust and acceleration. As a characteristic parameter of AE, ring down count (RDC) is able to quantify the deformation process of the soil slope. Moreover, acceleration and RDC can reflect the sudden change of the slope state and, hence, can be effective indicators for the early warning in a progressive landslide.

High strength structural (HSS) steels are widely used in many construction equipment and infrastructures. Currently, there is a substantial demand of Non-Destructive Testing of these steel structures. In this research, the electromagnetic technique was utilised to assess the plastic damage in a typical HSS steel (i.e. Q690 steel). The results showed that the magnetic hysteresis loop of this material changed apparently after the tensile deformation, and the relevant magnetic parameters such as coercivity, remanence, and maximum permeability were sensitive to the cumulative plastic strain. The results demonstrated that there is a good coherence between the plastic damage evolution and the magnetic parameters variation, which indicated that the electromagnetic technique is an effective method to assess the plastic damage of HSS steel.

Typhoon disaster represent one of the most prominent threats to public safety in the Macao Special Administrative Region (SAR) of China and can cause severe economic losses and casualties. Prior to the landing of typhoons, affected people should be evacuated to shelters as soon as possible; this is crucial to prevent injuries and deaths. Various models aim to solve this problem, but the characteristics of disasters and evacuees are often overlooked. This study proposes a model based on the influence of a typhoon and its impact on evacuees. The model’s objective is to minimize the total evacuation distance, taking into account the distance constraint. The model is solved using the spatial analysis tools of Geographic Information Systems (GIS). It is then applied in Macao to solve the evacuation process for Typhoon Mangkhut 2018. The result is an evacuee allocation plan that can help the government organize evacuation efficiently. Furthermore, the number of evacuees allocated to shelters is compared with shelter capacities, which can inform government shelter construction in the future.

To investigate the influence of inlet temperature and velocity of mold cooling water on the heat transfer effects in a continuous casting mold, a three-dimensional fluid flow and heat transfer coupled model was established, containing steel, copper tube and cooling water zone. Using Fluent, this model simulated the flow and heat transfer of liquid steel and cooling water, solidified shell growth, and heat transfer through air gap and mold fluxes. Furthermore, the accuracy of the model was verified by comparing the shell thickness and temperature fields in this study with those from other studies. The model results suggested that the inlet water temperature notably affects the temperatures of the mold cold surface. If the inlet water temperature exceeded 313 K, the highest temperature of the cold surface surpassed the boiling point of water, which could be a reason for billet rhomboidity. An increase of 0.49 m∙s−1 in water velocity diminished the adverse effects of an increase of 4 K in inlet water temperature. Off-squareness can be prevented in the actual production process by following this method.

This paper reports a novel use of magnetic technique to characterize the degradation in mild steel within the elastic range. Firstly, the mild steel specimens were stretched to several different kinds of stress within the elasticity. After the tensile test, a shift of hysteresis loop was observed in the tensile specimen, and the variations of magnetic parameters such as Coercivity (Hc), Remanence (Br), maximum permeability (µm), and hysteresis loop area (S) were also evident. When the tensile stress increases to the elastic limit (310 MPa), the Hc increased 16.44% compared with the original specimen, which manifested the variation of the magnetic property in mild steel. The magnetic property variation in material are closely interrelated with its microstructure change. The existence of internal residual stress/strain as well as the dislocation structure change are the main factors affect the magnetic property. The experiment results revealed that the magnetic technique was sensitive to the microstructural change in the mild steel, which has the promising potential to characterize the material degradation at the early stage.

This paper reports the plastic damage evolution in low carbon structural steel and its NDT evaluation. The SEM observations reveal that the voids initiation, growth, coalescence, micro-crack propagation, and macro-crack formation are the main failure forms. The EBSD results show that with the increasing plastic strain, the KAM and ρGND within grains in LC steel increased continuously. Meanwhile, the BS value and the IPF maps quality decreased significantly. Besides, the TEM observations show that the plastic strain induced dislocation density increase and inhomogeneous dislocation distribution in LC steel, the dislocation nets structures were developed at the later plastic stages, which consist of high-density dislocation tangles. Also, the magnetic hysteresis-loop changed distinctly after the plastic strain, and the Coercivity is sensitive to the change of dislocation structure/density. Therefore, the electromagnetic technique can be utilized to assess the plastic damage in LC steel.

Earthquakes are one type of natural disaster that causes serious economic loss, deaths, and homelessness, and providing shelters is vital to evacuees who have been affected by an earthquake. Constructing shelters with reasonable capacity in the right locations and allocating evacuees to them in a reasonable time period is one disaster management method. This study proposes a multi-objective hierarchical model with three stages, i.e., an immediate shelter (IS) stage, a short-term shelter (STS) stage, and a long-term shelter (LTS) stage. According to the requirements of evacuees of IS, STS, and LTS, the objective of both the IS and STS stages is to minimize total evacuation time and the objectives of the LTS are to minimize total evacuation time and to minimize total shelter area. A modified particle swarm optimization (MPSO) algorithm is used to solve the IS and STS stages and an interleaved modified particle swarm optimization algorithm and genetic algorithm (MPSO-GA) is applied to solve the LTS stage. Taking Chaoyang District, Beijing, China as a case study, the results generated using the model present the government with a set of options. Thus, according to the preferences of the government, the determination can be made regarding where to construct ISs, STSs, and LTSs, and how to allocate the evacuees to them.

Complex urban ecosystems are relatively fragile in the context of climate change. Given this fragility and the large numbers of urban inhabitants, it is important for researchers and government regulators to assess the adaptation capacity of urban areas with respect to climate change. Currently, there are few studies that have evaluated such adaptation capacity across different regions and periods. In this study, a framework and method are established to assess the adaptation capacity of Chinese cities and urban agglomerations (UAs) with respect to climate change by integrating an SPRR (Source, Pathway, Receptor, Response) model with the Intergovernmental Panel on Climate Change (IPCC) assessment framework. We develop an indicator system for exposure, sensitivity, and resilience and use the set pair analysis (SPA) method to evaluate the adaptation capacity of 12 typical UAs in China. Results show that (1) adaptation capacity levels show wide variation across China, with the majority of cities and UAs having either high or low levels of capacity and a minority having a moderate level of capacity; (2) inland UAs have low adaptation capacity because of low resilience and sensitivity, whereas eastern coastal UAs have high adaptation capacity, for their high resilience and sensitivity; and (3) higher climate change exposures are distributed predominantly in central China. A pronounced economic disparity exists between western inland regions and eastern regions, with the latter having higher levels of economic development and superior infrastructure. The regional economic inequalities and spatial variation in climate variability observed in China are also characteristics shared by many other countries and regions, suggesting that our results may be generalised to other countries and regions. We propose that underdeveloped regions should seek to improve infrastructure and funding directed towards improving adaptation capacity, whereas developed regions should improve their ability to monitor climate change and its impacts.

It has been demonstrated that climate change is an established fact. A good comprehension of climate and extreme weather variation characteristics on a temporal and a spatial scale is important for adaptation and response. In this work, the characteristics of temperature, precipitation, and extreme weather distribution and variation is summarized for a period of 60 years and the seasonal fluctuation of temperature and precipitation is also analyzed. The results illustrate the reduction in daily and annual temperature divergence on both temporal and spatial scales. However, the gaps remain relatively significant. Furthermore, the disparity in daily and annual precipitation are found to be increasing on both temporal and spatial scales. The findings indicate that climate change, to a certain extent, narrowed the temperature gap while widening the precipitation gap on temporal and spatial scales in China.

Ecological security assessment aims at identifying an ecosystem’s stability, recognizing the ability to maintain ecological health under various scenarios of ecological risks. In this study, we focus on the ecological security of Liao River Basin not only in terms of directly considering the sustainable development of the basin itself but also in terms of its importance as part of an ecological macro-control for northeast China. We built a “structure-quality-process” analytical framework to assess the ecological security of Liao River Basin. Our results showed that (i) land conversion from cultivated to artificial surfaces represented a dramatic change occurring in the region; (ii) the requirements of regional sustainable development would not likely be satisfied in regard to the given ecosystem services provided by the basin due to poor spatial coordination capability; and (iii) the priority areas for optimizing the ecological security patterns of the basin include the upstream and the downstream regions. The “structure-quality-process” assessment framework provides a dynamic perspective of ecological security and also considers the relationships and functions of the internal structures and processes of the ecosystem. The optimization of ecosystem structures and processes is essential and forms the basic measures and key content of macro-control for well-structured ecological security patterns.

As one of the important research areas of public safety and sociology, the study of mass incidents is inseparable from the support of a large number of real cases data. However, there is a lack of available and reliable mass incidents databases in academic circles in China. Using the news retrieval approach, this paper builds a case database of mass incidents in China from 1998 to 2014 based on the GIS system. Then the spatial-temporal distribution rules of these mass incidents data are analyzed from the perspective of geography. Our research effectively integrates the temporal attributes, spatial attributes, organizational attributes and violence attributes of mass incidents. The results show the hot areas and temporal distribution of mass incidents and mass violence, and reveals the main triggers of these events.
