摘　　要：以“胜利作业3号”自升式修井平台的固桩架结构为研究对象,通过建立精细有限元分析模型,对其进行了3种作业状态下的应力及变形分析,并根据分析结果,研究了该结构在各种工况下的强度安全性。所得结论对类似结构的设计、分析及平台安全性评价具有一定的参考价值。The paper investigates the behavior of the jack house structure of jack-up platforrn 'Shengli No. 3' under three load conditions. The digital modei for local structures is first established. The results for the stress and deformation are obtained by applving the precise finite elements method. Based on the numerical results, the safety of the local structure is assessed. The conclusions drawn from this paper are very valuable to the design, analvsis and safety assessment of similar structure.
