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.
