摘　　要：本文设计了一种平弧板组合式透空堤结构,基于物理模型试验讨论了不同相对潜深、相对波高、相对板宽及相对板间距等因素对该新型透空堤结构不同测点处的波浪压力及所受波浪总力的影响。研究结果表明,大部分情况下,上述影响因素对该新型透空堤不同测点处的波浪压力影响较为显著。相对潜深为-0.05时各测点正压值与负压值均较小,相对潜深为0时,结构所受的正压值与负压值最大。当相对波高从0.10增大为0.17时,正压值与负压值均增大。随着相对板宽在一定范围内的减小,多数情况下正压值与负压值均有所增大。当相对板间距变化时,对上层平板下表面和下层弧板上表面测点压力影响显著;大部分情况下,上述影响因素对该新型透空堤的波浪总力影响也较为显著。相对潜深为0时,正向垂直总力最大,相对潜深为0和0.05时负向垂直总力较大。当相对波高从0.10增大为0.17时,垂直总力与水平总力均有增大。相对板间距变化时,不同相对板间距的变化对平弧板组合式透空堤所受波浪总力影响较小。This paper designed a combined horizontal with arc plate type open breakwater dike structure.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 influence of wave pressure and total wave force received at different measurement points,based on the physical 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 breakwater.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 pressure 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 vertical 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 horizontal with arc plate type open breakwater.
