摘 要: 含有不連續(xù)面的巖石力學(xué)系統(tǒng)，在沿不連續(xù)面的滑動過程中，其響應(yīng)結(jié)果與滑動的位移、滑動的速度密切相關(guān)。該文對此現(xiàn)象進(jìn)行了理論分析，指出在一定的滑動速度范圍內(nèi)，滑體隨著滑動位移的積累，滑動速度發(fā)生突變。

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
