Based on the deepwater geological and hydrological conditions, and the soil parameters, a steel sheet pile cofferdam FSP IV supporting method of the closed button Larsen type is developed. According to the actual stress conditions of the steel sheet pile, the Midas-Civil software is used to establish the three-dimensional structure of the double-wall steel cofferdam in space and the three-dimensional simulation is carried out for the overall model to check the analysis. According to different stages of steel sheet pile construction, 6 kinds of load conditions are selected in the calculation, and three most adverse conditions are analyzed with respect to structural deformation, the moments in steel sheet pile, and the brace forces, through numerical simulations and the monitoring of displacement in the construction process, to better predict the trends of the supporting structure and to meet the needs of construction, in view of saving investment, shortening the construction period, and improving social and economic benefits.
