浅谈钢板桩围堰在浅海区桥梁中的应用

Application of Steel Sheet Pile Cofferdam in the Bridges at Shallow Sea Area

文章以厦门某海湾大桥的钢板桩施工实践为例,对浅海区桥梁下构施工方案进行探讨,对比分析了钢吊箱围堰、钢套箱围堰、钢板桩围堰三个施工方案的经济性与技术性,确定采用钢板桩围堰施工方案,并对其设计要点、施工技术及注意事项进行了介绍。

With the steel sheet pile construction practice in a bay bridge of Xiamen as the case,the article discussed the lower-frame construction program of a bridge in shallow sea area,conducted the comparative analysis on the economic and technical performance of three construction programs of steel suspending cofferdam,steel boxed cofferdam and steel sheet pile cofferdam,determined the application of steel sheet pile cofferdam construction program,and introduced its design keypoints,construction techniques and precautions.
