Abstract：This paper designed a combined horizontal with arc plate type open breakwater dike struc-ture.The factors such as different relative diving depth,relative wave height,relative plate width and relative plate spacing were discussed for the new type of open breakwater dike structure and the influ-ence of wave pressure and total wave force received at different measurement points,based on the phys-ical model test.The study results showed that,in most cases,the above-mentioned influencing factors had significant effects on the wave pressure at different measuring points of the new type of open break-water.The positive pressure value and negative pressure value of each measuring point were small when the relative latent depth was-0.05,and when the relative latent depth was 0.The positive pres-sure value and negative pressure value of the structure were the largest.When the relative wave height increased from 0.10 to 0.17,the positive pressure value and the negative pressure value increased.As the relative plate width decreased within a certain range,the positive pressure value and the negative pressure value increased in most cases.When the relative plate spacing changed,the pressure on the lower surface of the upper plate and the upper surface of the lower arc plate had a significant impact.In most cases,the above-mentioned influencing factors also had a significant impact on the total wave force of the new type open breakwater.When the relative diving depth was 0,the total positive vertical force was the largest,and when the relative diving depth was 0 and 0.05,the total negative vertical force of the wave was larger.When the relative wave height increased from 0.10 to 0.17,the total ver-tical force and the total horizontal force both increased.When the relative plate spacing changed,the change of different relative plate spacing had little effect on the total wave force of the combined hori-zontal with arc plate type open breakwater.
