摘　　要：系统分析了海洋移动式桩基平台就位时，桩靴发生滑移的原因、力学机理和地基破坏模式。提出了计算桩靴水平力的方法。模型试验验证计算方法的正确性，为这类平台重复就位时桩靴是否发生滑移，提供了实用评价方法。Abstract The reason and mechanic mechanism of sliding of jack up unit during re siting and the failure mode of foundation are systematically analyzed. On this base, a calculating method for the horizontal force acting on spud can by soil is presented. The accuracy of the calculating result is verified by model test and a practical appraise mathod for the sliding of spud can during re siting proposed.
