摘要
基于渤海JZ20-2导管架海洋平台,把原海洋平台的导管腿替换成不锈钢钢管混凝土结构,并且在海洋平台上增设预应力拉索,提出自复位不锈钢钢管混凝土-钢组合导管架海洋平台的概念。利用有限元软件ABAQUS建立了4种不同拉索布置方式的自复位组合海洋平台模型,对不同形式的海洋平台进行冰荷载工况下的减振性能分析和极端冰荷载作用下的自复位性能分析,分析结果表明自复位组合海洋平台具有明显的减振控制效果和一定的自复位能力。
Based on the Bohai JZ20-2 jacket offshore platform,this paper proposes the concept of self-centering stainless steel tube concrete-steel composite jacket marine platform,replacing the duct legs of the original offshore platform with stainless steel tube concrete structures,and adding prestressed cable on the offshore platform.Four kinds of self-centering combined ocean platform models with different cable arrangements were established by using finite element software ABAQUS.The vibration reduction performance analysis of different types of offshore platforms under ice load conditions and the self-centering analysis under extreme ice loads show that the self-centering combined offshore platform has obvious damping control effect and certain self-centering ability.
