【摘要】 应用摩擦实验装置，在法向压力σ＿ｎ＝１０～１２０ＭＰａ下研究了孔隙压变化速率对岩石错动面滑动行为的影响。当孔隙压增压速率较大时，具粘滑振荡特性的岩石错动面仍将发生粘滑振荡，当孔隙压增压速率较小时，错动面发生稳定滑动，当增压速率介于上述两者之间时，错动面则呈粘滑－稳滑转化。以上结果对地震前兆和地震控制研究有重要意义。更多还原

【Abstract】 In order to understand relation between earthquake activity and the variation of pore pres-sure，this work studied the effect of pore pressure rate on the sliding behavior between rock sur-faces,with constant normal stresses ranging from 10 to 120MPa. The result shows that，withhigh increasing rate of pore pressure，surfaces with low increasing rate of pore pressure，slidingbehavior was characterized by stable sliding，and there occurred a transition between the twomodes with a moderate increasing rate. The above mentioned result is important in future research on the precursory phenomena ofearthquake and earthquake control.更多还原
