摘　　要：以海南省文昌市清澜大桥为例,开展了大跨径斜拉桥工程场地地震安全性评价研究,给出了大跨径斜拉桥桥梁工程场地地震动参数确定的过程,还进行了场地特性分析及结构、基础、土体共同作用的探讨,以及给出了场地土层地震反应分析过程,可供相关工程项目设计人员参考和借鉴。Taking Qinglan Bridge in Wenchang City of Hainan Province as an example, the seismic safety of engineering site of long-span cable-stayed bridge is evaluated and studied. The process of determining the ground motion parameters of long-span cable-stayed bridge engineering site is given. The site characteristics are analyzed. The interaction of structure, foundation and soil mass is discussed. The process of analyzing the site soil seismic response is given. The reference can be provided for the designers of the relative engineering projects.
