湖滨路运河桥主桥设计及施工

Design and Construction of Hubin Road Canal Bridge

湖滨路运河桥主桥是拱梁组合体系桥梁,跨径布置为50 m+95 m+50 m。该桥为斜弯桥且桥宽达到38 m,施工不能影响主跨通航及边跨下道路通行。根据这些特点,采用了先梁后拱的施工方法,主桥主跨采用纵、横向挂兰结合的品字形悬臂浇注,边跨采用临时墩和支架的施工方法。还阐述了桥梁施工过程中的施工控制及成桥动静载检测的情况。

Hubin Road Canal Bridge is a beam-arch combination system bridge. The span arrangement is 50 ＋95 ＋50 m. In this paper,the bridge details of structural design and construction are presented. The bridge is an oblique and curved bridge of 38 m wide, the navigation clearance and the road clearance under side span must be satisfied. According to the characteristics of the bridge, the girder was constructed first and the arch afterward. The bridge main span was constructed by using cantilever construction method and the side span was constructed by using trestle construction method with temporary pier. The whole process of the construction control and the dynamic/static load test after the construction are presented in the paper.
