水库地震地质判别标志的研究

STUDY ON THE GEOLOGICAL DISTINGUISHING MARKS FOR RESERVOIR SEISMICTY

本文研究了中国水库诱发地震的地质构造总体环境，从中提取出诱发水库地震的八项地质判别标志。同时进一步将它们划分为一般性和特征性两类地质判别标志，前者在水库地震和天然地震中均可出现，后者一般是水库地震中所特有的标志，是判断发生水库地震的王要地质判据，故在水库选址、最低限度在大坝选址时，要避开具有明显诱发水库地震的地质标志地段。

by studying the general environment ofgeological structure for the reservoir-induced seismicity in China, the author summarized 8 geological distinguishing marks induce the which couleinduce the reservoir seismicity. These geological distinguishing marks were further divied into 2kinds, i. e., the common marks and special marks. The former could be seen boh in reservoirseismicity and in naturcal earthquakes, but the latter are Peculiar marks for reservoir seismicityand are main geolocal evidences to distinguish the reservoir seimicity. So, areas where exist obvious reservolr-induced seismicity geological marks should be avoided during the selection of theeservoir site or at least the selection of the dam site.
