摘要
根据工作区潜在震源区划分、潜在震源区地震活动性参数和地震动衰减关系，进行场地地震危险性分析，得到不同概率水平下场区相应地震烈度和基岩水平加速度峰值及其反应谱。根据场地工程地震条件划分不同地质单元及相应的场地类别，进行不同概率水平的地震反应分析计算，确定地震动设计参数。
After delimiting potential earthquake sources in a working area, determining of seismicity parameters in potential earthquake sources, and from attenuation relation of ground motion, we have made an analysis of seismic risk for both these eraeas. We abtained earthquake intensity of different probability and horizontal peak accleration at the bed rock as well as response spectrum. From the statistics of earthquake intensity attenuation a basic intensity of the sites was obtaimed. Based on the engineering seismologcal conditions we have classified geological units and types of sites, calculated seismic response of different probability, and determined ground motion parameters for design.
