本文介绍了我国八个水库地震的概况,总结了水库地震的一般特点,同时讨论了与成因有关的几个问题。指出库水沿周围岩石向深处的渗漏及入渗库水的封闭环境是主要的诱发条件。除构造应力外,岩体的重力可能是另一种更具普遍意义的发震初始应力。水库地震属粘滑机制。它与岩溶密切相关。 This paper introduces the general situation of eight reservoir earthquakes in our country, summarizes the general characteristics of reservoir earthquakes, and discusses some problems related to the cause. It is pointed out that the leakage of reservoir water along the surrounding rock and the closed environment of infiltration reservoir water are the main inducing conditions. In addition to tectonic stress, the gravity of the rock mass may be another, more general, initial seismic stress. Reservoir earthquake is a stick-slip mechanism. It is closely related to karst.
