贵州南盘江天生桥水电站水库地震预测
|
摘要
天生桥水电站水库地处扬子准地台和右江褶皱带的结合部,该部属构造运动强应变带,地质情况异常复杂;库区又同时处在中国现今高值构造应力带内,其应力强度为中强水平,内动力地质灾害当属中上水准,经研究坝址区及水库水域线外20km范围内有发生构造地震和水库诱发地震的可能性;其发震水准在315～511级之间,最大震级可达55+级,烈度达Ⅶ度。
The reservoir of Tianshengqiao hydroelectric station in Nanpanjiang of Guizhou occurs in the connection between Yangzi paraplatform and Youjiang folded zone which belongs to strongly strain field of structural act and keeps extremely complex geological condition.Also,the reservoir lies in the strain field of premium structure, the degrade of strain standsat middle-level and the geological cataclysm of inner power is above the middle-upper level.After the analysis within the district of dam site and the range out of reservoir liner by 20 km , it is possible that the earthquake of structure and of reservoir prompt would be happen.The earthquake magnitude is between the range of 3 15-5 11 degrees,and once happened to be the most earthquake magnitude which comes to 5 5 degrees and VII earthquake intensity
