摘要

基于岩石摩擦滑动变形场的非均匀特征，开展了岩石蠕滑和黏滑两种形式的摩擦滑动规律研究。采用双面摩擦模型试验方法，以数字散斑相关方法作为观测手段，分别研究了岩石蠕滑和黏滑变形过程中围岩位移场等值线、变形场非均匀统计指标、变形能密度与滑动面滑动速度演化及规律。结果表明：围岩位移场等值线分布能较好地反映滑动面阻滑特征，其中强阻滑区域的位移等值线呈弧状且分布较稀疏，弱阻滑区域的位移场等值线呈平行状且分布较密集；岩石蠕滑过程中，非均匀统计指标呈现波动增长特征，岩石黏滑过程中，非均匀统计指标呈现出突变跳跃特征。岩石蠕滑过程中不同区域的滑动速度均呈加速与减速滑动的交替状态，滑动面上各点滑动趋势不同；岩石黏滑过程中不同区域的滑动速度均出现突变。岩石蠕滑过程中不同区域上的变形能密度均处于积累与释放的波动状态，岩石黏滑过程中不同区域变形能密度产生突变。

Abstract

Based on the non-uniform characteristics of rock friction and sliding deformation field

the friction and sliding laws of creep-slip and stick-slip were studied

respectively. By means of double-sided friction model experiment

using digital speckle correlation method as the observation method

the evolution and laws of the displacement field contour

the non-uniform statistics of the deformation field

the deformation energy density and the sliding velocity of the sliding surface in the processes of creep-slip and stick-slip deformation of rock were studied respectively. The results showed that: the distribution of contours in the surrounding rock displacement field could better reflect the characteristics of sliding surface resistance

in which the contours in the strong resistance sliding area were arch-shaped and distributed sparsely

while the contours in the weak resistance sliding area were parallel and distributed densely. In the creep-slip process of rock

the non-uniform statistics showed the characteristic of fluctuation growth

while in the stick-slip process of rock

the non-uniform statistics showed the characteristic of mutation and jump. In the creep-slip process of rock

the sliding speeds in different areas were in alternating state of acceleration and deceleration. In the stick-slip process of rock

the sliding velocities in different areas were abrupt. In the creep-slip process of rock

the deformation energy densities in different areas were all in the fluctuation state of accumulation and release

while the deformation energy densities in different areas in the process of stick-slip were abrupt.
