ABSTRACT The berm revetment with a Seabee slope has been widely used in coastal defense structures. It is necessary to understand the distribution of wave-induced uplift pressure as it may cause serious damage to the cover layer of the revetment. Therefore, a series of physical experiments are carried out to quantify the uplift pressure on the revetment under various wave conditions. It is found that the freeboard of the berm is a key parameter which categorizes the laboratory results into two groups. Under negative freeboard, the distribution of uplift pressure on the upper slope is similar to that on the lower slope. Additionally, the maximum uplift pressure on both upper and lower slopes is strongly related to the surf-similarity parameter ξ p. Under positive freeboard, the uplift pressure on the lower slope is significantly larger than that of the upper slope. The maximum uplift pressure on the lower slope is similar to that of the conventional rubble mound revetment. At last, Empirical equations are proposed to estimate the maximum relative uplift pressure under positive and negative freeboards.

Seabee 斜坡护堤上的波浪诱发抬升压力

摘要 带有 Seabee 斜坡的护堤护岸已广泛用于海防结构。有必要了解波浪诱发的抬升压力的分布，因为它可能对护岸的覆盖层造成严重的破坏。因此，进行了一系列物理实验，以量化各种波浪条件下护岸的抬升压力。发现护堤的干舷是将实验室结果分为两组的关键参数。在负干舷下，上坡的抬升压力分布与下坡相似。此外，上坡和下坡的最大抬升压力与冲浪相似性参数 ξ p 密切相关。在正干舷下，下坡的抬升压力明显大于上坡。下坡最大抬升压力与常规碎石墩护岸相似。最后，提出了估计正负干舷下最大相对抬升压力的经验方程。
