摘要

依托工程实例阐述桥梁承台采用无底钢套箱围堰施工过程,施工期间结合常见问题,通过调查分析查明原因,采取优化法兰盘结构设计、提高套箱刚度、提高套箱整体稳定性等措施,有效解决问题。
        Based on engineering examples,the construction process of bottomless steel casing cofferdam for bridge cushion cap is expounded.During the construction,the causes of common problems shall be identified through investigation and analysis,and the problems were effectively solved by taking measures such as optimizing the flange structure design,improving the stiffness of casing and box,and improving the overall stability of casing and box.
