摘　　要：浙江路桥是一座鱼腹式铆接钢桁架结构的百年老桥,其位于上海市区苏州河上,属于上海市市级不可移动文物。为彻底修缮浙江路桥,将全桥整体移运至岸上维修厂房内大修,并于大修完成后移运回原位。采用有限元分析软件Midas对浙江路桥关键施工工序及成桥运营状态进行计算,同时指导施工过程及设计。计算结果显示各施工工况下结构安全,且成桥状态满足运营要求。本研究对于同类桥型维修加固施工及设计提供了参考借鉴。The Chekiang Road Bridge is a Fish-bellied riveted steel truss bridge,and already crossed the Suzhou River for one century cross in Shanghai..It is an important architectural and heritage of Shanghai.The rehabilitation process was finished in the temporary steel workshop on the bankside to make a thoroughly maintenance,then the bridge was shifted to its original position with the reverted procedure.The finite element software MIDAS was used to simulate the key rehabilitation processes and finished state of the Chekiang Road Bridge.The calculation results gives guidance to the construction and design.The results show that the structure of the bridge is safe during shifting and operation process,which can be referred for the rehabilitation of the similar projects.
