| 摘 要： | 开孔沉箱的开孔率是影响其消浪性能的重要参数,迎浪面上的开孔范围也会影响开孔沉箱的消浪性能。通过物理模型试验,测量了不同开孔率情况下开孔沉箱前的波高,采用多点法分析了波浪反射系数,研究了其消浪效果,给出了波浪反射系数与沉箱开孔率之间相互关系的试验结果;同时,通过试验研究了开孔沉箱的开孔区域上下端距静水位高度对沉箱消浪性能的影响,对比了两种不同开孔沉箱断面宽度情况下波浪反射系数。

| Abstract: | The opening rate and the opening area's position are important parameters which influence wave attenuation characteristics of perforated caisson.The wave height in front of the caisson with different opening rate was measured through physical modeling.The multipoint method was used to analyze the wave reflection coefficient,and the experiment results of the relationship between the opening rate and the wave reflection coefficient were given.Moreover,the influence of the opening area's position on wave atten... |
