摘要

根据设计的实验装置．对含有单一滑面岩石试件滑动过程进行模拟实验研究，得到了滑动过程、动摩擦阻力系数、阻尼系数等随滑动速度的变化规律，同时测得动摩擦力系数、阻尼系数随压力的变化关系。实验证实在一定的速度范围内，随着滑块的相对滑动速度不断增加，阻尼力反而减小，这种现象就是负阻尼。
With the experimental apparatus designed, an imtating test study of the sliding process for the single fault rock sample was carried out. The rules for the variation of the sliding process, the dynamic friction coefficient, the damping coefficient were obtained. At the same time, the relations between the dynamic coefficient and the normal pressure, the damping coefficient and the normal pressure were measured. The test proved that, within a certain scope of velocity, the damping force decreases with the increase of the ve-locity of the sliding block, which is defined as the negative damping.
