| 摘 要： | 工程场地地面运动峰值加速度是强震区城市发展规划、抗震防灾的重要依据,也是工程建筑抗震设计的基本参数。本文在研究秦皇岛市区域地震地质环境和地震活动规律的基础上,确定了区域潜在震源区及相应的地震活动性参数。将该市工程场地划分为规则网格,采用地震危险性分析的概率方法,计算出各场地在各不同年限内所遭受到的不同地震危险性概率水平。最后,编制出了供一般工业与民用建筑设计使用的,按50年10％给定概率水平的秦皇岛市地面运动加速度预测图。

| Abstract: | The peak acceleration of ground motion will surely provide important ba- ses for long-term city planning and earthquake strategy and is also the basic parameter of seismic design for a project. Based on the study of regional seismic environment and seismic periodicity, the potential seismic source zones and their activity parameters are determined. The whole city area is divided into regular retwork and the probability level of seismic risk at each joint in different period is calulated by means of fault-rupture model. A prediction map of ground motion peak acceleration is offered of Qinhuangdao city in terms of 50 year period with the risk probability of 10%. The map can be used for common industrial and civil building seismic design. |
