水库地震是因水库蓄水作用导致库区地质环境和区域应力变化,引起库区附近地震的现象。“触发地震”和“诱发地震”是根据成因机制的区别而对水库地震的分类。本文梳理和总结了自水库地震的概念提出以来,人们对于水库地震成因机制的分析,并就触发地震和诱发地震的不同分类进行了探讨;同时结合国内水库地震关于坝高、库容、岩性和震级方面的特征发现,无论是触发地震还是诱发地震,都是多方面因素综合作用的结果,但不同水库具有不同的地质环境和区域应力状态,各类成因机制在不同类型的水库地震中占比也不同。最后,作者对现今水库触发地震和诱发地震研究的不足进行了讨论,提出应结合其他人类工程活动所引发的地震一同分析。
Reservoir earthquake is caused by the reservoir water storage reservoir geological environment and regional stress changes, causing the earthquake near the reservoir area phenomenon. “Earthquake triggering” and “Earthquake triggering” are based on the classification of reservoir earthquakes based on the genetic mechanism. This paper reviews and summarizes the analysis of the genetic mechanism of reservoir earthquakes since the concept of reservoir earthquakes was proposed, and discusses the different classification of triggered earthquakes and induced earthquakes. In the meantime, combining with the analysis of the relationship between dam height, reservoir capacity, lithology and The characteristics of magnitude show that both the triggered earthquake and the induced earthquake are the result of a combination of many factors, but different reservoirs have different geological conditions and regional stress states, and all kinds of genetic mechanisms account for different types of reservoir earthquakes Also different. Finally, the author discusses the shortcomings of current reservoir-triggered earthquakes and induced earthquakes, and proposes that the earthquakes should be analyzed in combination with other human-engineering activities.
