| 摘 要： | 对初始安装阶段的桶型基础进行了研究，分析了不同长度及水深时结构所受的负压，将结构简化成一端固定、一端自由边界条件的圆柱薄壳。针对筒化模型，采用经典的薄壳理论对结构进行了理论分析，推导出结构在负压作用下的挠度、弯矩等的解析表达式，并研究了桶长、半径等形状参数对结构的影响；同时以Ｅｕｒｏｐｉｐｅ１６／１１Ｅ导管架平台的桶形基础为实例进行计算，并与有限分析的结果作了对比，得到了较为满意的结果。根据文中方

| Abstract: | The structure of bucket foundation in the initial installation stage was investigated, suction with different length and water depth were analyzed in detail and the foundation was modeled as a cylindrical thin shell with fixed free boundary condition. According to the above mentioned model, the strength analysis of bucket foundation under suction was developed using the classical thin shell theory. And, the corresponding equations of structural displacement and moments were derived, the influence to the structure of length and radius was analyzed also. The Europipe 16/11 E jacket was calculated as an example and the results from calculation were contrasted with those from FEM analysis. The program on the basis of this method is convenient and suitable for budget and evaluation in practice. |
