| 摘 要： | 本文根据岩石摩擦的自锁模型,通过数值模拟讨论了围压和围压介质刚度对粘滑及其应力降的影响。结果表明:围压的增大有利于发生粘滑;粘滑应力降随围压的增大而增大;天然地震应力降低于室内粘滑应力降是由围压介质刚度引起的。

| Abstract: | In this paper,we put forward a self-lock model of rock friction, reflecting the relationship of confining pressure and Stick-slip. In addition, we discussed the influences of confining pressure and confining stiffness on stick-slip and its stress drop with numerical simulation. The results indicate that: 1. The increasing of confining pressure is advantageous to stick-slip. 2. The stress drop of stick-slip increases with the increasing of confining pressure. 3. That the stress drops of natural earthquakes are not as great as that of laboratory experiment is caused by confining,stiffness. |

| Keywords: | stick-slip stable-sliding stress drop confining stiffness |
