Acoustic emission based mechanical behaviors of Beishan granite under conventional triaxial compression and hydro-mechanical coupling tests

Beishan area is now considered as a potential site of high-level radioactive waste (HLW) repository. In order to understand the mechanical behavior of Beishan granite, conventional triaxial compression (CTC) and hydro-mechanical (HM) coupling tests are conducted on Beishan granite. An acoustic emission (AE) monitoring system is employed to estimate the rock damage evolution during the tests. The testing results show that the compressibility of...
