Abstract: Natural joints play an important role in the stability performance of rock engineering. To deeply understand the shear mechanism of natural joints (i.e., tensile fracture or shear fracture), direct shear experiments and ...

Abstract: This study investigates the impact of two different coal-bearing metakaolin (CMK) powders, characterized by varying specific surface areas, on the partial replacement of cement and its resultant effect on the sulfuric acid ...

Abstract: Based on a large amount of real-time microseismic monitoring data and hundreds of rockburst cases of different types stemming from the construction of deep tunnels at Jinping Mountain Hydropower Station, Sichuan Province, ...

Abstract: Rockbursts are a common form of disaster that occur during the construction of deep tunnels in hard rock. This is especially the case in the breakthrough stage of excavation, when even more attention should be paid to the ...
