摘要
结合胜利埕岛油田导管架平台,探讨了在海水均匀腐蚀和受冰载荷作用条件下,造成浅海导管架平台构件损伤的原因;开发出构件等效刚度的计算模块,进行了平台结构强度分析,并运用有限元法计算平台在环境载荷下的极限承载力;对导管架平台进行了安全可靠性分析。
The paper discusses the cause of the damage of shallow sea tubular platform in the condition of the sea water corrosion and ice load. The calculation module of the components＇equivalent rigidity is built to analyze the structural strength of the platform. In addition, the finite element method is used to calculate the limited carrying capacity and the safety reliability analysis of the tubular platform is made.
