摘　　要：为提高深水桥梁承台围堰施工安全性、防水性、稳定性,文章依托京滨高铁北辰特大桥跨青龙湾减河连续梁工程为例,结合BIM技术对深水桥梁承台围堰结构构建三维模型,在常规双壁钢板技术的基础上进行优化,着重探讨施工现场如何制作符合工程需求的双臂钢围堰结构,然后在对口支撑和双菱形斜撑为围堰稳定性提供支持的同时应用U形拉森钢板桩、H形钢共同制作新型钢板桩,并使用斜杆、竖杆支撑对口支撑竖向层以强化结构抗变形性能,工程施工结束后质量良好,施工期间并未发生安全问题。In order to improve the construction safety,waterproof and stability of deep-water bridge bearing platform cofferdam,this paper takes the continuous beam project of Beichen super large bridge across qinglongwan Jianhe river on Beijing Binhai high-speed railway as an example,combines BIM Technology to build a three-dimensional model of deep-water bridge bearing platform cofferdam structure,optimizes it on the basis of conventional double wall steel plate technology,and focuses on how to make a double arm steel cofferdam structure that meets the engineering requirements at the construction site,and then applies U-shaped Larsen steel sheet pile and H-shaped steel to make a new type of steel sheet pile while providing support for the stability of the cofferdam,and uses inclined rods and vertical rods to support the vertical layer of the opposite mouth support to strengthen the deformation resistance of the structure.The quality of the project is good after construction,and no safety problems occur during construction.
