金汇港斜拉桥异型主塔钢混结合段施工技术

Construction Technology of Steel-concrete Composite Section of Special-shaped Pylon of Jinhuigang Cable-stayed Bridge

摘要:

以金汇港斜拉桥为例，针对其异型主塔钢混结合段定位、吊装和混凝土浇筑的重难点施工技术，从定位支撑设计、精准吊装就位、钢筋和预应力钢束施工控制、混凝土施工工艺等方面提出对应的措施，为同类工程的施工提供经验参考。

Abstract:

Taking the Jinhuigang Cable-stayed Bridge as an example, focusing on the important and difficult construction technologies in the positioning, hoisting and concreting of steel-concrete composite section of its special-shaped pylon, the corresponding measures for the design of positioning support, accurate hoisting in place, construction control of rebar and pre-stressed steel beam, and concrete construction technology are put forward, which can be referred for the construction of the similar projects.
