Basalt fiber, as a natural silicate fiber, has excellent engineering performance in high and low temperature resistance, high fracture strength, toughness, shear and elastic modulus in nature. Shotcrete was widely used in tunnel lining, slope support, coal mine roadway and other projects. With the continuous development of shotcrete technology, scholars found that adding fiber to shotcrete would greatly improve the performance of shotcrete. Compared with traditional plain shotcrete and steel fiber shotcrete, shotcrete incorporated with basalt fiber can dramatically improve the bending resistance, toughness and durability, therefore effectively improving the engineering performance of concrete structure, such as lining support. This paper summarized and discussed the mechanical properties, early age performance, durability and practical applications of basalt fiber reinforced concrete with a focus on basalt fiber shotcrete (BFSC). Meanwhile, it focused on the engineering performance improvement and enhancement mechanisms of basalt fiber as a mineral admixture into shotcrete, and assessed the deficiencies existing in the current research. Eventually, the suggestions and prospects for future BFSC related research were proposed.

Due to its Lagrangian nature, Smoothed Particle Hydrodynamics (SPH) has been used to solve a variety of fluid-dynamic processes with highly nonlinear deformation such as debris flows, wave breaking and impact, multi-phase mixing processes, jet impact, flooding and tsunami inundation, and fluid–structure interactions. In this study, the SPH method is applied to solve the two-dimensional Shallow Water Equations (SWEs), and the solution proposed was validated against two open-source case studies of a 2-D dry-bed dam break with particle splitting and a 2-D dam break with a rectangular obstacle downstream. In addition to the improvement and optimization of the existing algorithm, the CPU-OpenMP parallel computing was also implemented, and it was proven that the CPU-OpenMP parallel computing enhanced the performance for solving the SPH-SWE model, after testing it against three large sets of particles involved in the computational process. The free surface and velocities of the experimental flows were simulated accurately by the numerical model proposed, showing the ability of the SPH model to predict the behavior of debris flows induced by dam-breaks. This validation of the model is crucial to confirm its use in predicting landslides’ behavior in field case studies so that it will be possible to reduce the damage that they cause. All the changes made in the SPH-SWEs method are made open-source in this paper so that more researchers can benefit from the results of this research and understand the characteristics and advantages of the solution proposed.
