详细介绍日本格型钢板桩结构规范中关于抗倾覆稳定性与地基承载力的计算方法，该方法概念明确、计算速度快，适用于工程计算。在格型钢板桩结构的抗倾覆稳定性计算中，结合格型钢板桩的几何特性和受力特点，根据转动点位置的不同提出4种典型的受力模型，在地基承载力计算中考虑了地基受偏心倾斜荷载影响的情况。利用编制的计算程序和相关计算软件针对参考文献中的工程案例进行验算，再将该方法应用到某跨海大桥人工岛围堰的结构计算中，进一步验证了该计算方法和计算程序的正确性。

The calculation method of stability against overturning and ground bearing capacity is introduced in detail, which can be found in Japanese Standards on celled steel sheet pile structure. The method is of clear concept, fast calculation speed, and the adaptability to engineering calculation. In the calculation of stability against overturning, four classic stressed models are put forward in consideration of the geometrical features and stressed characteristics of celled steel sheet piles as well as different run-on points. The influence of eccentric tilting load on ground is considered in the calculation of ground bearing capacity. The compiled computing program and relevant software are used to check the engineering cases, which have been described in the reference literature. In addition,the method is applied in the structural calculation of artificial island cofferdam of one sea-crossing bridge,which proves further the correctness of the above method and program.
