Relying on the Algeria Ore Terminal Project,we propose a double-row-cylinder structure,and analyze numerically its static response under the action of the wave crest with Abaqus.There are two schemes to connect the two rows of the cassions,which are using simply supported slab and rigidly coupled slab.The latter form is better in deformation coordination with a smaller maximum base stress,and it’s easy to meet the requirement of the slab strength.However,it needs a higher cost.As for the scheme of using simply supported slab,the slab gaps can be with or without filling the flexible material.In the former situation,the soil pressure takes on a linear distribution with the bigger value in the upper place,which is opposite to the latter situation.The load transmitted by the connecting slab will account for a considerable proportion,and base stress is greater in the latter situation.
