海工结构物浅基础稳定性的可靠度分析

Reliability analysis on the stability of shallow foundation of ocean structures

应用可靠度理论对渤海某油田软粘土地基上工作的沉垫式基础的稳定性进行了可靠度分析 ,阐述了各个设计指标的变化对分项系数及可靠度指标的影响规律 ,并将分析结果与该标准中规定的分项系数进行了比较。

In this paper, a procedure for reliability analysis on the stability of shallow foundation of ocean structures is presented. As an example, the stability of a cushion type foundation of a self raised platform is analyzed by performing the proposed approach. The influence of a variety of soil properties and the loads to the reliability index are analyzed, and the calculated partial factors compared with those given in the design code.
