| 摘 要： | 目前，在我国发生岩溶塌陷型水库地震的震例已有10余座，震级不大，但对库区居民影响较深，个别地方还造成房屋的轻微破坏。本文通过对塌陷型水库地震的特点、岩溶发育的规律、影响岩溶发育的因素进行分析，归纳出不同的岩溶发育阶段与水库地震的关系。并结合多年实际工作经验，总结出根据岩体性状和空间展布、岩溶水文地质及岩溶管道系统与库水的关系等评价岩溶塌陷型水库地震的可能性、可能地点及震级上限的方法。

| Abstract: | At present, more than ten instances of karst collapsing were induced earthquake in reservoirs of China. It made great influence on the life of residents who live in the area of reservoir, even though these earthquakes are not strong enough, and light damages of house in individual place also taken place. In this paper, the characteristics of KCIE, the law of karst development and the factors of effect on karst development are analyzed. The relations between stages of karst development and reservoir-induced earthquake are concluded. On the basis of many years engineering experience, the method, which values the possibility of KCIE, possible location and maximal magnitude of earthquake according to the relationship between water level of reservoir and features of rock mass, spatial distribution, krast hydrogeological condition and the karst passage system, are summarized. |
