岩体结构面对应力波的传播影响很大。关于波在接缝中传播的理论和实验研究已经得到了广泛的研究（例如，Kendall和塔博尔，1971年; Schoenberg，1980年; Pyrak-Nolte等人，1990年; Zhao和Cai，2001年; Zhao等人，2006 a，B; Perino等人，2010年; Li和Ma，2010年; Li等人，2010年），重点是关节刚度，入射角，关节数量和关节间距对波传播的影响。与理论和实验研究相比，数值模拟提供了一个方便，一种研究节理岩体中波传播的经济方法，特别是对于无法获得理论解且难以进行实验的复杂情况，例如，波在包含多个交叉节理组的岩体中的传播，并涉及多个隧道开挖和地下爆炸（Zhao等人，1999年）。
Discontinuities in rock masses greatly influence stress wave transmission. Theoretical and experimental studies on wave propagation across joints have been extensively studied (eg, Kendall and Tabor 1971; Schoenberg 1980; Pyrak-Nolte et al. 1990; Zhao and Cai 2001; Zhao et al. 2006a, b; Perino et al. 2010; Li and Ma 2010; Li et al. 2010), focusing on the effects of joint stiffness, incident angles, number of joints, and joint spacing on wave propagation.Compared with theoretical and experimental studies, numerical modeling provides a convenient, economical approach to study wave propagation across a jointed rock mass, especially for complicated cases where theoretical solutions are impossible to obtain and experiments are difficult to conduct, such as wave propagation in a rock mass containing several intersecting joint sets and involving multiple tunnel excavation and underground explosions (Zhao et al. 1999).
