摘　　要：水库诱发地震是指在特殊的地震地质环境下,由于水库蓄水和水位变化引发的地震。目前水库诱发地震研究手段主要有:一是在建坝前查清库区的地震地质条件,应用地震地质类比法,对水库诱发地震的危险性进行评价和预测可能最大震级,作为大坝抗震设计的依据;二是布设小孔径遥测数字地震监测台网对水库诱发地震进行监测和分析。本文对应用小孔径遥测地震监测台网的理论依据、监测目的和监测技术进行了探讨。Reservoir-induced earthquake is earthquake which is caused by reservoir storage in some special seismic geological environment. At present, there are two main methods to study reservoir-induced earth- quake. The first method is to investigate seismic geologic conditions in reservoir area, at early constretion stage of dam, evaluate the risk of reservoir induced earthquake, and predict its maximum magnitude, which provides a basis for the seismic design of dam. The second is to monitor and analyze, which pro- vides a basis for the seismic design of seismic monitoring network. In this paper, theoretical basis,monitor- in~, ouroose and monitorin~ technologies of small aoerture seismic monitorin~ network are discussed.
