摘　　要：为了解决基岩浅埋条件下的钢板桩设计与施工问题,文章结合扶典口西江特大桥5~#墩钢板桩围堰工程,介绍了浅埋钢板桩围堰设计方案,并建立平面有限元模型对各工况下的钢板桩围堰结构进行受力变形分析,同时对浅埋钢板桩围堰施工的关键问题进行探讨。实践表明,该围堰结构下洪水影响较小的水域,结构应力及变形均能满足要求。To solve the design and construction problems of steel-sheet piles under shallow-buried bed- rock conditions,and in combination with the steel-sheet pile cofferdam project of Fudiankou Xijiang Super-large Bridge # 5 Pier, this article introduced the shallow-buried steel-sheet pile cofferdam de- sign program, established the plane FEM model to conduct the stress and deformation analysis of steel-sheet pile cofferdam structure under each work condition, and discussed the key issues in the construction of shallow-buried steel-sheet pile cofferdam.Practices showed that the structural stress and deformation of water area in this cofferdam structure which is less affected by the flood can meet the requirements.
