大跨径混凝土斜拉桥主梁合龙段施工技术研究

Study on Construction Technology for Main Girder Closure Segment in Long-Span Concrete Cable-Stayed Bridge

以上海辰塔公路跨越黄浦江大桥工程的主梁合龙段施工为例,对合龙段的施工流程、合龙用吊架、合龙段临时锁定、合龙段混凝土浇筑和合龙段预应力施工等进行了详细的论述,可为今后大跨径混凝土斜拉桥主梁合龙段的施工提供借鉴和指导。

Taking the main girder closure segment construction of Shanghai Chenta highway crossing the Huangpu river as an example, the construction process of closure segment, closure hanger, temporary closure lock, concrete pouring and pre-stressed construction of closure segment have been described in detail, which can provide references and guidance for the future construction of main girder closure segment in the long-span concrete cable- stayed bridge.
