从动力学系统稳定性的观点提出了滑坡灾害发生的一种新机制,认为滑体滑动的稳定与否是与滑动的阻尼性质密切相关,稳定的滑动是由于系统存在正阻尼,非稳定的滑动是系统出现负阻尼所致,同时提出判别边坡滑动系统稳定性的准则。
A new mechanism of landslide hazard is proposed from the viewpoint of dynamic system stability. It is considered that the stability of sliding is closely related to the damping property of sliding. The stable sliding is due to the positive damping and unstable sliding of the system It is caused by the negative damping of the system. At the same time, the criterion for judging the stability of slope sliding system is put forward.
