钢桁梁悬索桥的顶推施工方法研究

Study on Jacking Construction Method of Steel Truss Girder Suspension Bridge

当跨越山谷的钢桁梁悬索桥架梁时,传统的施工方法具有较大的局限性。对此进行方案比选,提出对施工条件要求较低、适用于钢桁梁悬索桥的顶推施工方法。以某山区悬索桥为例,讨论了顶推方案在应用中的若干细节问题,可为同类桥梁的主梁架设提供参考。

The traditional construction method has the greater limitation when erecting the steel truss girder suspension bridge crossing valley.The article compares and selects the schemes,puts forward the lower construction requirement of jacking construction method suitable for the steel truss girder suspension bridge.As an example of a suspension bridge in mountain area,the article discusses several details of the jacking scheme in its application,which can be referred for the erection of the main girder of the similar bridge projects.
