Abstract: Wave propagation across rock masses containing structural planes has been an important subject of rock dynamics. The stresses of deep rock mass will affect the mechanical properties of rock structural plane, and then affect the stress wave propagation across rock mass. Based on the time domain recursive analysis method (TDRM), quantitative analysis for the interaction between stress wave and a nonlinear rock structural plane is carried out in this study, so as to deduce the wave propagation equation. The deformation of the rock structural plane is assumed to satisfy the Barton-Bandis model (B-B model) in the normal direction and satisfy the Coulomb slip model in the tangential direction. For some special cases, such as horizontal or vertical distribution of structural plane and horizontal distribution of wave front, the calculation model and wave propagation equation are simplified. Through comparison, it is found that the rock mass stresses have obvious influence on wave propagation characteristics. Parametric studies about the effects of rock mass stresses characteristics, joint characteristics and incident wave frequency on stress wave transmission and reflection coefficients are finally conducted.

Key words: stress wave, wave propagation, rock mass stresses, rock structural plane, transmission and reflection coefficients
