摘要

依据弹性波理论，应力波斜入射线弹性节理时会发生波场分解。根据入射、透射及反射各波形的不同到时，运用离散元软件UDEC模拟应力波在含倾斜节理岩体中的传播并计算其透射、反射系数，并分析其波型转换规律。应力波斜入射单节理时，模拟得到的透射、反射系数随节理刚度、入射角度的变化规律，与已有的理论解是吻合的。应力波斜入射一组平行节理时，随着节理间距的增大，其同类波的透射系数Tpp、Tss先增大后减小，最后趋于稳定值；节理条数越多，Tpp、Tss越小。此外，不同条数的节理，透射系数达到最大值的临界节理间距值基本一致，但趋于稳定时的节理间距值随节理条数的增加而逐渐增大。

Abstract

Based on the elastic wave theory

the stress wave field will separate when it is oblique incidence across a linear elastic joint. The propagation of stress waves in rock mass including oblique joints is analyzed; and the computation of transmission and reflection coefficients is conducted with a universal distinct element code (UDEC)

according to different approaching times of incident

transmitted and reflected waveforms. When stress waves is oblique incidence across a single joint

the simulated relationships between transmission coefficients and joint stiffness

incident angle agree well with the classic theoretical solutions

as well as the reflection coefficients. Furthermore

the situation of stress waves propagate through a set of parallel joints is analyzed. The results show that the transmission coefficients Tpp

Tss of the same kind wave firstly increase to maximum values and then decrease to stable values with the increasing of joint space; and the stable value becomes smaller when the number of joints is larger. Additionally

the critical values of joint space when transmission coefficients approach maximum values are approximately identical for different numbers of joints; but the inflection values of joint space for the situation of stable values gradually become larger with the increasing of joints number.
