Abstract: This study mainly focuses on the transport process of broken rocks in geological fractures, faults, and karst conduits. Because previous research mainly focused on the influencing factors of adverse geological conditions, ...

Abstract: Stratum cavity collapse induced by water and sand leakage in a subway tunnel is a sudden urban geological disaster, which can cause serious casualties and economic losses. In response to the hazards of stratum cavity ...

Abstract: Rock-like materials generally manifest both strain-softening and pressure-dependent effects. The critical plastic strain corresponding to the residual state also increases with the confining pressure. In this case, all of ...

Abstract: The shear behavior of intact cubic sandstones was studied under constant normal stiffness (CNS) conditions using self-designed equipment. A series of direct shear tests on intact sandstone blocks was conducted with initial ...
