工程场地地震动参数的确定

摘要

A certain engineering site in Xianyang is taken as an example in this paper. Firstly, seismic geology condition of the engineering site is expounded, secondly,on the basis of analysis of seismic hazard of the engineering site, one-dimension earthquake response of soil layer is analysed and computed, and finally parameter of earthquake ground motion of the engineering site is determined for earthquake-resistant design as a proof.%以咸阳某工程场地为例，首先阐述了场地的地震地质条件，然后在场地地震危险性概率分析的基础上，对场地土层进行一维地震反应分析计算，确定了该工程场地地震动参数，为抗震设计提供了依据。
