钢吊箱在深水高桩承台施工中的设计应用

Design and Application of Steel Boxed Cofferdam to the Construction of Deep Water High-rise Pile Caps

以溆怀高速公路沅水大桥主桥深水承台施工为例,介绍了钢吊箱的设计要点、结构组成及施工方法。该吊箱结构简单,受力明确,安拆迅速,操作方便,效果显著,值得同类工程参考。

Taking the example of deep water cap construction in Yuanshui Bridge main bridge of Xuhuai Expressway as an example,this paper introduces the design points,structure,and construction methods of the steel boxed cofferdam.This boxed cofferdam has a simple structure,definite forces,and can be installed and dismantled fast,easy to operate,with significant effects,which can be reference to similar projects.
