钢桁桥维护改造工程难点及对策

摘要:

我国早期建设了大量的钢桁桥，近年来，根据使用养护情况以及交通发展需求，这些桥梁已经陆续进入大修改造期。通过大修改建，可以在延长桥梁使用寿命的同时优化提高桥梁的使用功能。本文通过上海苏州河上的浙江路桥的大修，总结了钢桁桥大修改建工程中的一些经验，以及在桥梁大修工程中采用EPC模式进行管理的优势，可供以后类似工程参考和借鉴。

Abstract:

A large number of steel truss Bridges were built in China in the early stage, in recent years, according to the maintenance situation and traffic development, these Bridges have entered the maintenance period. Through reconstruction, the life of the bridge can be extended while the service function of the bridge can be optimized. Through the reconstruction of Zhejiang road bridge on Suzhou River in Shanghai, this paper summarizes some experience in the reconstruction of steel truss bridge, and the advantage of EPC mode for management in the bridge reconstruction project, which can be used as a reference for similar projects in the future.
