摘　　要：双排钢板桩围堰的整体稳定计算可将其看作为整体的重力支挡结构,采用圆弧滑动法计算;对中部填土宽度较大的双排钢板桩围堰,采用了传统经验简化计算方法和有限元法两种方法验算对比,并最终采用了传统验算方法的计算结果。通过工程实例,对其设计方法进行了探讨,对类似工程的围堰结构设计有一定的参考借鉴价值。The overall stability calculation of double row steel sheet pile cofferdam can be regarded as the overall gravity retaining structure,and the circular sliding method was used for calculation;for the double row steel sheet pile cofferdam with wide filling between the double row steel sheet pile,the traditional experience simplified calculation method and finite element method were used for comparison,and the calculation results of the traditional method were finally adopted.The design method was investigated by an engineering example.It provides some reference value for the cofferdam structure design of similar projects.

关 键 词：双排钢板桩围堰 整体稳定计算 结构内力计算 有限元法
