The paper carries out the static and dynamic analysis of the inclined pile-gravity structure under the action of berthing impact force by ABAQUS.By comparing the dynamic displacements with the static displacements of the inclined pile-gravity structure,the dynamic amplification factor of the impact force is get.The amplification effect changing rule of different effective impact energy is discussed.The results show that the dynamic amplification coefficients of the composite structures under the same effective impact energy are the same.In the design of inclined pile-gravity structure,when the ships effective impact energy is greater than 1 350.4 kJ,the coefficient of the berthing impact force is 1.5 according to the standard,which is small;when the design vessel type is 300 thousand DWT,it is recommended to take 2.12.
