摘　　要：本文依托某市域铁路项目头陀特大桥,采用有限元分析软件模拟复杂地层条件下跨越溪流的钢栈桥结构进行分析验算,确保其强度、刚度及稳定性满足规范要求。验算中分别采用结构自重、模拟上部移动荷载、水流力、风荷载等荷载组合模拟不同工况分析,验证了钢栈桥的受力性能,并总结了施工注意事项,可为类似工程提供参考。This article relies on a certain urban railway project,the Toutuo Extra Large Bridge,and uses finite element analysis software to simulate the steel truss bridge structure crossing streams under complex geological conditions for analysis and verification,ensuring that its strength,stiffness,and stability meet the requirements of the specifications.In the verification calculation,different load combinations such as structural self weight,simulated upper moving load,water flow force,and wind load were used to simulate different working conditions for analysis.The stress performance of the steel wharf was verified,and construction precautions were summarized,which can provide reference for similar projects.
