Abstract—This study is based on a simulation of suction and compound suction written in Plaxis 3D finite element software. Unlike a conventional suction foundation, a composite suction foundation has a plate-like structure in its upper part, which improves the axial and lateral bearing capacity of the foundation. In this study, sedimentation data obtained from Changhua, Taiwan are used as the inputs, and bearing capacity is evaluated for a composite suction foundation under two-directional loading. By changing the diameter of the upper plate, the length–diameter ratio of the suction bucket, and the eccentricity of the load, relevant stress behaviors of the foundation are simulated.
Index Terms—Plaxis 3D, composite suction foundation, stress behavior.
