摘　　要：通过对我国已发生诱发地震的29座水库资料整理,分析其库容、坝高对诱发地震的影响以及蓄水时间长短对诱发地震的发生概率和震级的影响关系,提出水库地震应分为二类或二个阶段。对福建及邻近地区的18座大中型水库进行统计,并对福建水口、棉花滩、街面水库及珊溪水库的多个方面进行了统计和综合类比分析,提出了水口水库和浙江珊溪水库发生诱发地震的主要因素。Through data collection from 29 reservoirs,where have occurred induced earthquakes in China,the authors analyzed the influence on induced earthquake caused by the storage capacity and the height of the dam,and also analyzed the influence on induced earthquake′s occurrence probability and the magnitude caused by the length of water storing time,proposed reservoir earthquake should be divided into two categories or two stages.Based on research of 18 large and medium-sized reservoirs in Fujian and its neighboring areas,including statistic and comprehensive analysis of Shuikou,Mianhuatan,Jiemian and Shanxi reservoirs,the authors present the main factors of induced earthquakes which occurred in Shuikou and Shanxi reservoirs.
