摘要：This article uses finite element software to simulate the internal force and deformation of pile-soil under the wave and ice load. The group pile foundation model is simplified in the plane as a single pile affected by other piles.Calculating wave force based on Morison Equation,The effect of wave force and ice load calculated with the measured wave force and ice load on the pile is compared. According to the time history curve, when the absolute value of acceleration is maximum, the curves of the bending moment, axial force, shear and displacement of the pile with the depth of the pile under the action of wave force, ice load and joint force are analyzed, the time history curves of pile top displacement under the combined action of wave force and ice load are analyzed,the displacement time history curves of different positions of piles are compared.Finally, the effect of buried depth, pile diameter and free length on the pile body interaction under the wave force and ice load is analyzed.
