摘要
工程场地动力分区评价（即地震影响小区划），是在工程场地地震危险性分析的基础上，根据场地岩土动力特征及地形地貌、地质构造条件等对地震动影响的反应程度，从而对不同类型场地的地震效应作出评价．其成果可做为建筑抗震设计、工程加固、震害预测与对策的制定及土地合理利用和总体规划布局的依据．本文以秦皇岛市青龙县城工程场地为例，进行了工程场地动力特征研究与分区评价及震害预测（即工程场地地震影响小区划）。
Dynamic character, zonation and evaluation on engineering site, in otherword, earthquake microzonation,which is on the baste of engineering sesmicanalgsis, evaluates ettects of earthquake of different site by anatysing rock and soil dynamic feature, landform and geological structure.The achivement of eawhquakemicroznation can be foundation of buildingssesmic design,engineering reinforce,sesmic prediction,making policy,land managing and long-term land arrangement. This paper is a example in engineering site of QinglongCounty,Qinghuangdao city. Earthquake microzonation of the engineering site is made.
