| Abstract: | 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. |
