斜拉桥主塔上横梁施工技术研究

Construction technology research on cable-stayed bridge of the main tower beam

运用桁架法进行斜拉桥主塔横梁施工能够充分发挥其结构特性及空间优势,有效保证施工质量及施工工期,结合辰塔公路越黄浦江大桥新建工程主塔施工的具体特点以及现场施工情况,选用桁架法施工上横梁,极大的缩短了总施工工期,为今后类似工程提供参考。

The use of truss law for cable-stayed bridge of the main tower beam construction can give full play to its structural characteristics and advantages of space,it’s effective guarantee of construction quality and construction period.With the specific features and site of the main tower construction of the new project of Chen-Ta highway which across the Huangpu River bridge,using truss method to construct beam,greatly shorten the total construction period,providing reference for similar projects in the future.
