摘要
金华-义乌-东阳市域轨道交通在上跨甬金高速公路,因桥下净空受限,采用了1-72m双线简支钢桁梁桥方案。文章对桥的结构形式、杆件尺寸、整体桥面系设计和焊接细节设计作了详细介绍,通过建立杆系和壳单元有限元模型对结构的强度、刚度、疲劳性能进行了验算。
Jinhua-Yiwu-Dongyang Urban Rail Transit crosses over Yongjin High-speed Railway, due to the headroom under bridge is limited,1-72 m simply-supported steel truss girder is adopted. The structure form,the size of the rod, the integral deck system and the welding detail design is introduced.The structure performance of strength, rigidity and fatigue is calculated by the finite element method of bar system and shell element.
