Grouting-efficiency evaluation is a key element in grouting-construction control. However, most existing grouting-efficiency evaluation models do not consider the hesitation and bounded rationality of experts and have difficulty in handling the problem of incomplete decision-making information generated by experts. Furthermore, the diversity of the evaluation indicators used can be further improved. This study conducts a comprehensive evaluation model to address these problems. An objective and reasonable fuzzy evaluation method is demonstrated through the integration of interval-valued intuitionistic fuzzy sets, prospect theory, and improved D numbers. The secondary permeability index is introduced to establish a more scientific evaluation indicator system. The proposed model is implemented in evaluating the curtain-grouting efficiency of a hydropower station, and its consistency, representativeness, and superiority are validated and analyzed.

The real-time compaction quality evaluation of earth-rock dam plays a pivotal role in ensuring dam safety. However, the current real-time compaction quality evaluation only takes the physical properties of compacted dam materials into account, which fails to characterize whether their mechanical property meets the requirements of deformation and destruction, and no quantitative heterogeneity of real-time compaction quality is studied. This paper presents a comprehensive evaluation method to address these problems. First, based on on-site tests, real-time physical and mechanical indices are obtained. Next, the analytic hierarchy process, extended by the interval model (i-AHP) method, is introduced for real-time compaction quality evaluation considering both these indices, and the hybrid compaction index (HCI) is firstly proposed based on the i-AHP method. Finally, an improved geostatistical analysis method (i-GAM) is developed to quantify the real-time compaction quality heterogeneity. A case study of an earth-rock dam project in southwest China demonstrates the effectiveness and advantages of the proposed method.

Core Rockfill dam is characterized by huge filling volume, multiple material sources and high strength of transportation to dam, which leads to a higher demand on organizational arrangement of transportation system, as well as on control of material sources on the construction site. Aiming at characteristics and main points of control over the process of materials transportation to dam, the real-time monitoring method of the whole process of materials transportation to dam for rockfill dam is proposed based on monitoring indexes and control criterion using Global Positioning System (GPS), General Packet Radio Service (GPRS) and Personal Digital Assistant (PDA) technology. Real-time automatic collection technology of the transportation process information and calculation and analysis of method of transportation parameters are also proposed. Application in practical engineering shows that mismatching loading or unloading of dump trucks can be discovered in time, wrong filling of dam materials can be avoided using the technology. It can also be used to calculate traffic density and strength of transportation to dam. The technology is an innovation of construction management method for rockfill dam, which has provided strong support for construction quality management and organizational arrangement.

Construction process reengineering (CPR) is used to reengineer the construction process of engineering project by using the thought and method of business process reengineering (BPR) to improve the efficiency of engineering construction. CPR theory provides improvement direction for construction project information management: On the data-oriented and function-oriented bases, it can realize the support of engineering construction project management information system for management process, and realize the objective of information integration and knowledge sharing under the premise of process optimization. The paper makes research on the process and method of construction project management process reengineering based on CPR theory, puts forward design thought for engineering construction project management information system based on CPR theory, and uses J2EE technology to set up information platform to realize the support for construction management process.
