Jack-up pile stabilizing platform is widely used in single pile foundation sinking construction of offshore wind power engineering. Therefore, it is of great significance to carry out research on vertical bearing characteristics of jack-up pile stabilized platform for safe operation of platform. The CEL numerical simulation method in the finite element software ABAQUS was used to analyze the bearing characteristics of a jack-up pile stable platform in the qidong sea area of jiangsu province. The following conclusions were drawn :(1) CEL numerical simulation method can effectively simulate the whole process of pile penetration into the stratum, and reveal the soil density evolution law in the process of pile penetration; (1) CEL numerical simulation is basically consistent with the characteristic curve of pile bearing capacity obtained in The Code for Marine Well Site Investigation; (3) It is recommended that the safe penetration depth of pile foundation is 10 m, which is located in soil layer ②-2 and silty clay layer. In this case, the pile foundation bearing capacity obtained by theoretical and numerical analysis is 4.0 MN. The research results can provide theoretical support for the safe operation of jack-up pile stabilization platform in Qidong Sea area, Jiangsu Province.
