扭王字块体护面潜堤加高方案

针对小型渔船在潜堤堤顶搁浅的问题，开展潜堤加高的方案设计及试验研究。通过同类工程对比提出采用扭王字块体直接堆叠加高潜堤的方案，并开展波浪物理模型试验对比3种设计方案。试验结果表明：扭王字块护面结构潜堤采用直接堆叠扭王字块进行加高是可行的。加高设计中堤身护面采用与下层相同规格的块体能够满足稳定要求也便于施工。当堤顶高程在设计高水位以上不足0.2倍设计波高时，堤顶块体质量采用外坡护面块体质量的1.5倍通常不够，须达到2倍以上。

Heightening scheme of Accropode submerged breakwater

In order to solve the problem of small fishing boat grounding on the top of submerged breakwater, we carry out the scheme design and experimental research on the heightening of the submerged breakwater.Based on the comparison of similar projects, we propose the scheme of directly stacking and heightening the submerged breakwater with Accropode, and carry out physical wave model test to compare the three design schemes.The experiment results show that it is feasible to heighten the submerged breakwater by stacking Accropode directly.In the heightening design, the block with the same specification as the lower layer can meet the stability requirements and is convenient for construction.When the crest elevation is less than 0.2 times of the design wave above the design high water level, 1.5 times of the weight of the outer slope protection block is usually not enough , and it should be more than 2 times.
