摘要
针对自升式钻井平台固桩区域桩腿柱壳结构承受局部较大水平力的受力特点，选用NASTRAN求解器对该区域结构进行高精度有限元模型应力分析，并对不同的加筋方案作了一些定性定量的分析对比，其结果可对设计和审图具有一定的参考价值。
Due to the larger horizontal force acting on the legs of jack-up platform in fixed wedged area,its shell structure has to be stiffened accordingly. A precise finite element analysis was camed out for the local stress on a cylindricalleg with longitudinal and horizontal ring stiffeners. The results of the analysis are discussed and presented in this paper.
