“…For the rock-concrete binary, the interface is usually a naturally weak surface with low tensile strength and is therefore susceptible to moisture migration, which can lead to unpredicted freeze-thaw damage. Furthermore, due to the peculiarities of the interface presence, the mode of moisture migration behavior is not well established [10]. Thus, the study of moisture migration and damage debonding at the rock-concrete binary interface under freeze-thaw action is a good academic prospect in terms of binary interface bonding in cold regions.…”

“…At the same time, the AE technique has often been used to study the destruction properties by recording the radiated elastic wave in the process of crack initiation, propagation and coalescence during rock deformation [25][26][27][28][29]. Meanwhile, in the study of AE characteristics in rock deformation tests, the analysis of the b value is also a focus [30][31][32][33]. The amplitudes of AE signals are always used for the b-value estimation, and amplitudes are usually divided by 20 to produce a b value comparable to that reported in the seismic literature [34][35][36].…”

“…In recent years, the research on the mechanical properties of shale is also an important trend. For example, Xie et al (2020) studied the influence of the loading rate on shale fracture behavior under dynamic and static loading conditions and found that the crack propagation rate and fracture toughness were positively correlated with the loading rate. Wang et al (2018) studied the geotechnical engineering characteristics of red shale and revealed the unfavorable factors of its geological environment.…”
