摘要
隔河岩水库蓄水前即开始对穿越库区的主要断裂进行监测，并设立了地震观测台网，蓄水后库尾区诱发了一系列微震，形成几次水库诱发地震高潮期。本文通过库区近4年的形变观测资料的初步分析，论述了蓄水后库区地壳的稳定性及诱发地震与断层活动的关系，探讨了今后诱发较大地震的可能性。
Before impoundment of Geheyan reservoir to monitor the major faults which cut through the reservoir area had been taken step, and the seismological network set up at the same time. After impoundment a series of Ancroquakes are induced at the reservoir tail area,and several peak periods could been identlfied. mough the prlmary analysls of deformation observed data of reservoir area in the last four years, the relation between the crustal stability and the induced earthquake and faulting in the reservoir area after impoundment have been discussed, and the probability of larger induced earthquake too.
