The research of simplification methods of boundary condition for legs of the offshore platform
Due to lack of recognized conclusions on the collision of truss jack-up offshore platform, when designers and inspectors study the collision performance of the jack-up offshore platform, they always rely on experience to select the simplification method of pile leg boundary conditions and various parameters required. The actual available equivalent boundary conditions of pile legs are not determined. To solve this problem, this paper selects the truss pile leg jack-up platform as the target platform for research. And modified the D-P constitutive model to established the "pile-soil" coupling model. At the same time, use the equivalent pile principle to established model. The finite element software ABAQUS is used for comparative analysis to determine the simplified boundary conditions which can be used for collision simulation analysis. The results can provide a reference for calculating the collision performance of truss jack-up offshore platform.
