岩体中常常具有各种结构面、弱面和软弱夹层。这使应力波在岩体中的传播过程十分复杂。应力波在这些结构面、弱面和软弱夹层的界面上将发生复杂的反射与折射,这对应力波的传播产生一定的影响。 The rock body often has various structural planes, weak planes and weak interlayers. This makes the propagation of stress waves in the rock mass very complicated. Stress waves will have complex reflections and refractions at the interfaces of these structural planes, weak planes, and weak interlayers, which will have a certain influence on the propagation of stress waves.
