摘　　要：考虑到自升式平台在不同海况条件下作业,其可变载荷、悬臂梁外伸长度等参数对抗台能力产生较大影响,为避免其导致结构损伤,采用有限元方法,通过多工况计算,分析环境载荷、可变载荷等参数对结构强度的影响,确定敏感因素,给出满足抗台要求的工况条件。When the jack up platform operates under different sea conditions,its variable load,cantilever extension length and other parameters have a great impact on the platform resistance.In order to prevent the risk of structural damage,the influence of environment loadings,variable load and other parameters upon the structural strength was analyzed in detail by using the finite element method,and the sensitive factors were determined.The working conditions being able to meet the requirements of anti-typhoon were given.
