In view of the construction situation of the vehicle-passenger ferry terminal and the characteristics of the engineering sea area of Sijiao island in Zhoushan，we take the high-pile bearing bench structure as the research object，contrast under different design three kinds of high pile bearing bench structure secondary waves wave height and transmittance，overtopping waves，the original design straight pile scheme and the revised schemes wave force through the wave section physical model test. In addition，we measure the water flow velocity at the crevice of the front wave baffle plate of the original design straight pile structure，integrate the whole physical model test to compare the test results of different schemes. The results show that the wave condition in front of the breakwater in the straight pile structure is worse than that in the inclined pile structure，while the wave condition behind the breakwater in the inclined pile structure is better. The structural design elevation is close to the wave action area，both overtopping and breaking wave impacts are strong，so the drainage and force of upper structure should be focused in the design.
