摘要/Abstract

摘要：

利用150例水库诱发地震震例和532个国内大型水库资料,使用灰色聚类方法,按库深、库容、区域应力状态、断层活动性、岩性介质条件和地震活动背景等6个诱震因素,统计出相应的发震比例数,以此作为水库地震预测指标。再根据长江三峡水库坝址区、香溪河口及仙女山断裂带过江段、泄滩西和巴东及神龙溪两岸的6个独立的诱震因素,评估各段的水库诱发地震震级上限。计算结果表明长江三峡水库坝址区震级上限<3级,香溪河口及仙女山断裂带过江段4～5级,泄滩西<3级,巴东北岸及神龙溪两岸震级3～4级。并得到了长江三峡水库蓄水后实际地震情况的验证。

Abstract:

In this paper,a statistical analysis is made using the gray clustering method on the earthquake inducing factors,such as dam height,storage capacity,regional stress state,fault activity,lithology medium conditions and seismic activity background,based on a database of reservoir-induced earthquakes,which includes 150 reservoir-induced earthquake cases and 532 large reservoirs data. Corresponding earthquake occurrence ratios are obtained and used as predictors for reservoir-induced earthquakes. According to the six quake-inducing factors,assessment is made on the maximum magnitude of reservoir-induced earthquake for the Three Gorges Reservoir dam area,the bayou of Xiangxi stream and the cross-river section of the Xiannushan Fault zone,the west Xietan,Badong,and on both banks of Shenlong stream. The results show that the upper-limit of magnitude at dam area is less than magnitude 3,that at the bayou of Xiangxi stream and the cross-river section of Xiannushan Fault zone is between magnitude 4～5,that at west of Xietan is less than magnitude 3,and that at the northern bank of badong and on both banks of the Shenlong stream is between magnitude 3～4.The results have been validated by the actual reservoir-induced seismicity after the impoundment of the Three Gorges Reservoir, with the M_L 2 earthquake at Xiaoxikou 4 km far away from the dam of the Three Gorges Reservoir on February 6, 2009, the M_S 4.1 earthquake at the bayou of Xiangxi stream and the cross-river section of the Xiannushan Fault zone on November 22,2008, the M_S 2.6 earthquake at the west Xietan on August 22, 2009, and the M_L 3.5 earthquake at the bank of Shenlong stream on December 14,2009.

Key words: gray clustering method, the upper limit of magnitude, assessment, reservoir-induced earthquake, the Three Gorges Reservoir
