摘要
以沅江大桥1#、2#墩为例,通过底节围堰入水方案比选、钢围堰拼装平台结构设计及其拼装、预压施工,总结了深水桥梁采用先堰后桩法施工时,双壁钢围堰拼装平台的设计与施工技术,对深水桥梁水中墩基础施工有很好的指导作用。
Based on the example of Yuanjiang bridge No. 1, No. 2 block, through comparison of the bottom section under- water cofferdam plans, steel cofferdam assembly platform structure design and assembly, preloading construction, the paper summarizes the design and construction of double-wall steel cofferdam assembly platform in the ＂pile after cofferdam＂ con- struction, which can be referred to the deep water bridge pier foundation construction.
