台风区跨海桥梁独立钻孔平台抗风浪设计

摘要

In connection with the (B0 ~B58)main pier foundation independent drilling platform of the highway and rail-way combined bridge over the Pingtan Strait of newly-built Fuzhou-Pingtan Railway under the complicated typhoon area sea conditions such as strong wind,high wave and urgent flow,we carry out a summary respectively from the aspects of the structure comparison of independent platform,the structure design calculation for drilling platform and its structural analysis during construction.It can provide a reference for similar engineering construction in future.%针对新建福州至平潭铁路平潭海峡公铁两用大桥（B0～B58）主墩基础独立钻孔平台所处风大、浪高、流急等复杂台风区海况下，分别从独立平台结构形式的比选，钻孔平台的结构设计检算以及施工过程中结构分析等方面进行了总结，为以后类似工程施工提供借鉴。
