The steel cylinder structure is generally used as a wharf revetment structure. It is necessary to evaluate the safety and stability of the steel cylinder structure as the retaining structure for offshore foundation excavation. In this paper, a large finite element software PLAXIS is used to simulate the safety factor and the structural displacement of the steel cylinder structure in the wave load and the excavation of the foundation. The calculation results show that the overall stability of the steel cylinder is 1.7 when the most unfavorable condition of excavating from the foundation to the bottom of the steel cylinder. The lateral displacement is 572mm, which meets the safety requirements of the structure. The steel cylinder structure can play a role as the water retaining structure of the cofferdam and the support structure of foundation when it was put into the non-permeable layer.
