摘要

摘要: 基于岩石块体摩擦滑动试验反映的特征规律 ,本文分析了岩块随时间滑动的界面阻抗机理 ,并建立粘滑位移弱化时反映滑动界面阻抗时间效应的模型公式阻抗松弛模型。

Abstract: Based on the experimental behaviours of rock blocks when sliding in the paper, the mechanism of rock interface friction resistance is analysed. At last, a model is proposed to describe time effect of the rock interface friction resistance when viscous sliding and displacement softening occur,the relaxation model of friction resistance.
