摘要
进行了自升式平台桩基的稳定性分析和结构优化分析,初步探讨了层状地基承载能力分析方法,建立了平台整体、桩和桩靴等的数值计算模型,通过分析优化了桩基结构,降低了桩与桩靴连接处的应力集中,对自升式平台桩基结构设计和平台作业的稳定性分析具有参考价值。
Stability analysis and structure optimization on jack-up platforms with pile foundations are finished.A analysis method of bearing capacity in layered soil is discussed.The numerical model is established and the pile-foundation structure is optimized.Stress concentration of connecting areas between piles and pile boots is reduced.The study has reference value for structure designs and stability analysis of jack-up platforms.
