Deep-water wharves are mostly located in the ocean with complex natural conditions.Under the action of ocean wave cyclic loading,many wharves have been seriously damaged and cannot be used before they reach the designed life.On account of special damages to the overall structure of the wharf under cyclic loading of ocean waves,according to the engineering experience,ANSYS software is used to establish the integral finite element model for foundation-pile-superstructure of high-piled wharf.With damage constitutions used,we established the empirical formula of sea soil softening coefficient,simulated and analyzed the damage and damage law of wharves after different operating years.The results show that the crack starts from the panel at the earliest and gradually develops to the bottom of the beam.However,the softening of foundation soil is out of step with that of concrete.Cracks that increase after 10 years start with the bottom of the beam.Therefore,the overall impact of cyclic wave loads on the pile-upper structure of wharf should be considered in designing,and according to the synergistic action mechanism between the actual pile foundation and the superstructure,corresponding measures make the design more scientific and reliable.
