摘要
把导管架海洋平台看作钢框架结构,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,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。通过渤海BZ28 1油田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。
The jacket platform is assumed as a steel frame structure and an optimum design method is proposed. The total weight of the structure is selected to be the optimal objective. The average diameter and wall thickness of the structural element are taken as design variables. Constraint conditions, such as strength, stiffness and stability, are taken into account. As an example, the oil deposition offshore platform BZ281 of Bohai oil field in china is numerated. The results show that the proposed method is significative in the design of the platforms.
