摘 要: 含有不连续面的岩石力学系统，在沿不连续面的滑动过程中，其响应结果与滑动的位移、滑动的速度密切相关。该文对此现象进行了理论分析，指出在一定的滑动速度范围内，滑体随着滑动位移的积累，滑动速度发生突变。

Abstract:The responding result of a rock machanics system, which contains discontinuous faces, is related closely to the displacement and velocity of sliding. This phenomenon has been analysed in the paper and a viewpoint is put forward, that is, in a certain range of relative slipping velocity, the catastrophe of slipping velocity occurs with the accumlating of slipping displacement.
Key words: discontinuous face rock sample catastrophe negative damping
