针对我国港口与海岸工程建设的需要,详细分析、介绍了不考虑地震荷载作用和考虑地震荷载作用两种情况下日本规范中格型钢板桩结构的计算方法。在抗剪计算中分别对泥面和格体底部进行验算;在稳定性计算中考虑结构几何特性和受力特点,根据转动点位置的不同提出4种不同的受力模型;在地基承载力计算中考虑地基受偏心倾斜荷载的影响;在板厚的计算中考虑了腐蚀的影响。之后针对理论公式按计算流程编写了计算程序,对某跨海工程人工岛围堰工程和其他三个工程的计算验正了计算方法和程序的正确性。与其他方法相比,日本规范法概念明确,计算速度快,适合工程计算,也适用于入土深度比较大的情况。
針對我國港口與海岸工程建設的需要,詳細分析、介紹瞭不攷慮地震荷載作用和攷慮地震荷載作用兩種情況下日本規範中格型鋼闆樁結構的計算方法。在抗剪計算中分彆對泥麵和格體底部進行驗算;在穩定性計算中攷慮結構幾何特性和受力特點,根據轉動點位置的不同提齣4種不同的受力模型;在地基承載力計算中攷慮地基受偏心傾斜荷載的影響;在闆厚的計算中攷慮瞭腐蝕的影響。之後針對理論公式按計算流程編寫瞭計算程序,對某跨海工程人工島圍堰工程和其他三箇工程的計算驗正瞭計算方法和程序的正確性。與其他方法相比,日本規範法概唸明確,計算速度快,適閤工程計算,也適用于入土深度比較大的情況。

A detailed description about the calculation methods for the cellular-bulkhead structure was given considering seismic loads according to the development of port and coastal engineering construction. The analysis of shear deformation shall be taken at the bottom of the cell or the seabed. In the analysis of overturning stability four equilibriu models were established in consideration of the structure’s geometry,force characteristics and rotation point position. The effect of the eccentric and inclined actions was taken in the analysis of ground bearing capacity and the impact of corrosion was taken in the calculation of cell thickness. Then a calculation program has been compiled to solve the expressions according to theoretical formula. The methods and the program proved to be correct compared with the results of three project examples in the reference and the result based on a cofferdam of the artificial island in a sea crossing project. The Japanese standards method had clear concepts and fast calculation speed. It is not only suitable in engineering application,but also suitable when embedded length ratio is larger.
