Abstract: Water inrush is one of the most serious threats to the construction safety of karst tunnels. Numerical simulation is one of the important means of underground engineering research, which is of great significance for revealing ...

Abstract: Tunnel excavation by cyclic blasting caused accumulative damages to the surrounding rocks, reducing the intactness of the rock mass. The blasting impact contributes to the formation of an excavation damaged zone (EDZ) ...

Abstract: Pareto archived dynamically dimensioned search (PA-DDS) is one of the meta-heuristic methods available to solve multiobjective reservoir operation problems. This study uses this method to optimize reservoir operation rules ...

Abstract: The transverse isotropic (TI) creep behavior of rocks was investigated using laboratory tests and constitutive modelling. Triaxial stepwise and multiple-stage creep tests were performed to investigate the TI creep behavior ...

Abstract: The structure of the layered rocks is characterized by oriented bedding planes, resulting in transverse isotropy in deformation and strength. An elastoplastic constitutive model was proposed for transversely isotropic (TI) ...

Abstract: Tunnel construction in mountain areas, especially in karst regions, is challenging due to complex hydrogeological conditions in such regions, such as water inrush disaster induced by water-bearing structures that may ...

Abstract: In the Jennings criterion, which is commonly used to estimate the shear strength of nonconsecutive jointed rock masses, the estimated values deviate from the actual values due to the criterion failure to consider the joint ...
