摘要
针对桁架桩腿自升式平台桩腿结构特点,介绍了桁架桩腿波浪和海流载荷计算及水动力系数选取方法,并以某一自升式平台为例,采用桁架桩腿"详细模型"和"等效模型"进行桁架桩腿波流载荷分析,通过研究确定采用桁架桩腿"等效模型"计算的波流载荷较"详细模型"计算的波流载荷要小,约为80%左右。
Aiming at structure characteristics of truss leg of deepwater Jack-up unit,the calculation method of the wave-current load on truss legs and the selection method of the hydrodynamic coefficient are introduced.Taking a Jack-up unit as an example,the wave-current load on truss legs are calculated with“detailed model”and“equivalent model”.It is found that the wave-current load on truss legs calculated by“equivalent model”is about 80%smaller than by“detailed model”in the research.
