Evolution of Natural Joints' Mesoscopic Failure Modes under Shear Tests: Acoustic Emission Investigation
Publisher: ASCE
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 ...
Spatial Fractal Structure of Microseismic Events for Different Types of Rockburst in Deeply Buried Tunnels
Publisher: ASCE
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, ...
Characteristics of Microseismicity during Breakthrough in Deep Tunnels: Case Study of Jinping-II Hydropower Station in China
Publisher: ASCE
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 ...
