双场点地震危险性分析方法及其应用
|
摘要
提出了双场点地震危险性分析方法,用以计算在相同地震构造环境中,相同地震作用下的相邻两个工程场点同时超越其给定地震动参数的概率.该方法是确定系统的危险段落、场点遭受的附加地震危险的有效工具.基于汶川MS8.0地震后大渡河干流及邻近地区的地震环境,以大渡河干流梯级水电站系统为例,确定了大渡河干流梯级水电站各个河段的地震危险性.其中危险性最高的3个河段是:龚嘴—铜街子河段、沙坪—龚嘴河段和大岗山—龙头石河段.
A bi-site seismic hazard analysis method is proposed to calculate the acceleration exceedance probability of the two nearby sites located in the same seismo-tectonical region and suffered the shaking induced by the same potential earthquake. This method is an effective tool for determining the dangerous segment of a linear spread system and calculating the additional seismic hazard from its neighbor site for a given site. Basing on the new seismic background after Wenchuan Ms8.0 earthquake and taking the cascade hydropower stations in the trunk stream of Dadu River as a study case,the seismic hazard of each reach is determined. The study result indicates that the most dangerous reaches are Gongzui-Tongjiezi,Shaping-Gongzui and Dagangshan-Longtoushi.
