“…Therefore, in karst areas, it is very important and difficult to maintain the stability of the tunnel's surrounding rock. To resolve these difficult problems, investigations based on theoretical derivations, numerical simulations, and physics experiments have been conducted by many scholars [17][18][19][20]. Ma et al [21] used the distinct lattice spring model (DLSM) to numerically investigate the effect of karst caves on tunnel stability.…”

“…[4][5][6][7][8][9][10][11] AE sensors capture acoustic signals and analyse them through data acquisition to obtain the location of the source of cracks within the material. [12][13][14][15] In this study, Xu et al [16] quantified the extent of damage within the material by AE energy signatures. dai et al [17] applied an acoustic emission (AE) system to study and analyse the distribution characteristics of the fracture process zone (FPZ) in Berea sandstone in a threepoint bending test.…”
