摘　　要：山区建设项目在进行场地类别划分时,同一场地可能存在不同场地类别,影响到抗震设计参数的选取。首先对场地等相关概念进行了阐述,然后通过实例说明了山区场地类别划分,最后采用PLAXIS对不同场地类别上的结构进行了地震反应有限元分析,得到了一些有益的结论。There may be different site categorise in the same site during the site classification of mountain area construction projects,which affects the selection of seismic design parameters.The concept of site and other related concepts are described,andthen the classification of mountain site category is illustrated by example.Finally,the finite element analysis of seismic response ofstructures on different site types is carried out by PLAXIS,and some useful conclusions are obtained.

关 键 词：场地类别 地震反应 有限元分析 场地反应谱
