摘　　要：平台在海上受风、浪、流、冰等水平载荷作用产生滑移 ,而土壤粘结力、摩擦力和土抗力是平台的抗滑力 ,桶基平台应满足抗滑稳定的要求 ,以保证平台的整体稳定性。介绍了浅海桶形基础平台受水平力作用时桶形基础的破坏模式及其计算方法 ,并阐述了抗滑稳定计算方法。The horizontal load actions of wind, wave, current and ice may cause the offshore platform sliding, and the platform sliding resistance includes soil cohesion, friction and soil resistance, so the bucket foundation platform should be designed to meet the requirements of stability against sliding to ensure the overall stability of platform. The failure modes of bucket foundation and their computational methods when the offshore platform is affected by the horizontal forces are introduced, and the computational methods of stability against sliding are also addressed.
