海堤前特殊地形对护面块体稳定性影响及对策

通过在波浪水槽内对海堤护面块体稳定性物理模型试验,发现在堤前存在特殊地形的条件下,波浪传播该区域后发生变形、破碎,形成的波能集中冲击范围内护脚人工块体,导致其失稳,进而使断面上整个护面块体向海侧滑移失稳。文章分析了块体失稳原因和影响因素,并从设计角度提出多种针对特殊地形下人工块体失稳的改善措施。

Influence of complex terrain in front of seawall on armor block stability and its countermeasures

Based on physical model test of armor block in ing of waves occur under the condition of special terrain. Then wave flumes, it is found that deformation and break- the artificial block within the range of possibilities is impacted by the concentration of wave energy, which results in the instability of toe protection armor block and the slippage of the whole armor blocks. In this paper, the reasons of block instability and the influence factors were ana- lyzed. From the point of harbor construction design, some improvement measures were put forward to solve the prob- lem of block instability owing to the special terrain.
