通过对波浪越浪量、波压力等要素的测定与分析,对超高水位及相应台风大浪下的海堤加高方案进行了初步探索。试验实例表明,在堤顶内侧设置一定高度的挡墙可挡住越浪水体下部的楔形连片水体,从而有效减少作用于海堤背坡的越浪量,该例中堤顶内侧挡墙的实测最大越浪压力达到148.8 kPa,作用位置可在挡墙底部或近底部。
通過對波浪越浪量、波壓力等要素的測定與分析,對超高水位及相應檯風大浪下的海隄加高方案進行瞭初步探索。試驗實例錶明,在隄頂內側設置一定高度的擋牆可擋住越浪水體下部的楔形連片水體,從而有效減少作用于海隄揹坡的越浪量,該例中隄頂內側擋牆的實測最大越浪壓力達到148.8 kPa,作用位置可在擋牆底部或近底部。

Through measurement and analysis of wave overtopping volume,wave pressure and other factors,this paper proposes a seawall heightening plan in response to super-high wave level,typhoons and huge waves.Experiments suggest that a certain retaining wall inside the seawall top can block the wedge-shaped water body of overtopping waves,effectively reducing the overtopping volume of the back slope.In this case,the maximum measured pressure is 148.8 kPa in the bottom or near bottom part of the retaining wall.
