摘  要:涔天河水库,蓄水40年未纪录到水库诱发地震。拟扩建工程,坝高113m,库容15.1亿m3。增加蓄水14亿m3后,是否会发生水库诱发地震,最大震级多大?依据地震构造背景、水库规模、水库蓄水后诱发最大震级的最大概率时间等,预测涔天河水库诱发地震最大震级不会大于4.7级。After Centianhe reservoir impounding 40 years, there is no reservoir-induced earthquake recorded. Expansion project is planed for that the dam height is 75m, and storage capacity is 1.51 billion m3. When increasing the volume of water by 1.4billion m3, whether or not reservoir-induced earthquake occurred, and how big can the earthquake get? According to seismotectonic background , reservoir scale, the maximum probability of time when earthquake of the maximum magnitude happen after impoundment, this paper predicts that the maximum magnitude of Centianhe reservoir-induced earthquake is less than 4.7.
