A Split Three-Characteristic Method for Stress Wave Propagation Through Rock Mass with Double-Scale Discontinuities
摘要
Discontinuities ranging from micro-defect to macro-joint widely exist in the natural rock mass, which significantly influence the stress wave propagation (Chen et al. in Rock Mech Rock Eng 49:2701–2709, 2016; Feng et al. in Eng Fract Mech 207:237–253, 2019; Niu et al. in Rock Mech Rock Eng 51:1347–1359, 2018).
