| 摘要: |
| 为优化自升式平台桁架式桩腿结构构型，采用参数化建模技术和SESAM的GeniE软件，对不同构型桩腿的结构强度和总体性能进行评估.选取拖航工况和自存工况进行分析，结合母型资料，拖航工况时选取不同的桩腿节距构型进行强度评估；自存工况时选取不同的弦管间距和桩腿节距构型对平台抗倾覆能力、最大支反力、锁紧力以及桩腿组件UC值进行计算.以满足强度和经济性最优为原则，结合各构型桩腿结构质量，给出最优的桩腿结构构型方案.该方法快速完成了某型自升式平台的桩腿构型选取,结果表明该方法是自升式平台设计初期桩腿结构选型和优化的有效方法.

| Abstract: |
| In order to optimize the structure configuration of the truss type legs of the self-elevating platform,the parametric modeling method and GeniE software of SESAM were adopted to evaluate the performance and strength of different leg configurations. Towing and survival conditions were analyzed in the study process. Series of leg bay heights were chosen for strength analysis under towing condition. Different leg configurations with chord spaces and bay heights under survival condition were chosen to calculate the anti-overturning capacity,maximum reaction of support,locking force and the UC values of leg components. Considering the leg weight,the optimal decision for the leg configuration was given according to the principle satisfying the optimized strength and economy. A certain jack-up unit leg design was finished rapidly by this method. The study result indicates that the present method is effective for leg configuration selection and optimization in the preliminary design stage.
