[摘要] 甬台温铁路温州站采用预应力混凝土框架结构，上部结构采用大跨度钢结构罩棚。根据工程设计中的特点，对结构整体进行了有限元分析，确定合理的结构布置形式。通过试验手段，分析了静荷载作用下体外预应力楼盖缩尺模型的破坏机理。为火车站大跨度楼盖结构设计提供了较好的参考与依据。

Abstract: Yong Tai Wen Railway Wenzhou station consists of multi-story prestressed concrete frames and span steel roof. According to the project's characteristic, the finite element method is applied to analyze the overall structural designs in order to determine the proper structural arrangement. Based on the results of the reduced scale tests, the failure mechanism of the extemal prestressing floor under static force is analysed. the fact of which provides a practical reference to the design of railway station.
