摘　　要：采用三维有限元计算方法对CB20B桶形基础海上采油平台进行了稳定性计算分析。平台工作期间在外部荷载如风力、波浪、冰力、海流等作用下,其抗倾、抗滑稳定性不仅与平台的整体结构有关,而且和海底土体的力学特性以及结构与土体的相互作用密切相关。分析结果表明CB20B桶形基础平台在设计条件下运行是较为稳定的。The 3-D FEM is used to calculate stability of the CB20B bucket foundation platform made by Drilling Technology Research Institute, Shengli Petroleum Administration Bureau. The stability of the platform is related to the whole construction of the platform, also to the mechanical propeties of oceanic soil in the foundation and to the act each other between the platform and the soil under wind, waves, ice and ocean current loading. The results of calculation show that CB20B platform is rather stability under the conditions of design.
