摘　　要：针对绥中36-1油田AⅡ井口平台上部组块载荷不能满足桩基承载力安全系数规范要求的问题,在总结抗冰结构设计实践的基础上,进行了模型冰试验。基于模型冰试验结果,提出了新的多腿柱导管架平台结构最大设计冰载荷的计算方法,解决了设计冰力与实际受力之间差别过大而导致的桩基承载力安全系数不能满足规范要求的问题,对今后井口平台、综合平台基础导管架抗冰设计具有一定的参考价值。To solve the problem that the upper loads could not meet with the safety demand for the pile foundation of SZ36-1 oilfield WHP-A Ⅱ , the ice model test was performed based on the experiences of former ice resistant structure designs. A new calculation method for the maximum ice load on multileg jacket is proposed to solve the problem that big difference between design load and actual stress could not meet the safety demand for pile foundation. The research could provide a well reference to the ice resistant structure designs.
