| 摘 要： | 本文把导管架海洋平台看作钢框架结构,考虑了桩-土-结构的动力相互作用,并把优化方法用于结构的抗震设计中.以结构的总重量最小为优化目标,以导管的平均直径和壁厚作为设计变量,考虑强度、刚度和稳定等约束条件.并以渤海油田BZ28-1储油平台为例进行了计算,计算结果表明,此方法对海洋平台的设计具有一定的参考意义.

| Abstract: | Jacket platform was assumed as steel frame structure and the pile-soil-structure interaction was considered.Optimum method was applied to aseismic design of structure.Total weight of the structure was selected to be optimal objectives.Average diameter and wall thickness of the structural element were taken as design variables.Constraint conditions such as strength, stiffness,stability were taken into account.As an example,the deposited oil Offshore Platform BZ28-1 of Bohai Oil Field in China was numerated.The results show that the proposed method is significative in the design of the platforms. |
