摘　　要：非洲几内亚湾区域某工程项目为实现对升级后的港口形成良好掩护效果建设防波堤结构,结合工程地质情况以及当地的施工条件,防波堤采用抛石斜坡堤结构。防波堤结构分别采用双联块体和扭王字块体两种块体作为护面结构开展了试验研究,通过计算分析以及物理模型试验对防波堤断面在波浪作用下的稳定性、越浪量和波后堤高进行验证,经对比分析两种块体均可以满足设计及使用要求,在稳定性上具有同级别的安全性,为类似工程设计提供了技术支撑。A breakwater was built to achieve a good shielding effect on the reconstructed port in Gulf of Guinea,Africa.Rubble mound slope dike served as breakwater based on local geological and construction conditions.Traditional and dual wave-dissipating blocks were used as armor structure,complete with the corresponding experimental research.Physical model tests,calculation and analysis were carried out to verify the stability of the breakwater section under the action of waves,overtopping amount and the height of dike behind waves.The comparative analysis results show that the above two blocks satisfy the design and use requirements,guarantee both stability and safety,and can provide technical support for similar engineering design.
