| 植物型生态护岸作为一种新兴的海岸防护方式，不仅具备护岸功能，还能有效促进海岸带生态修复。然而，如何构建植物型生态护岸并对其消浪效果进行定量评估，仍是一个有待解决的问题。因此，采用数值模型模拟和物理模型试验两种方法对其进行了研究。通过在Navier-Stokes方程中引入植物与流体作用项，采用标准Smagorinsky紊流模式描述植物与波浪作用的紊流效应，并改进MAC算法（marker-and-cell method）和波浪表面追踪法，开发了数值模型；通过物理模型试验验证了数值模型，构建了植物消浪阻力系数经验公式。研究结果表明：构建的数值模型可以反映植物的消浪效果，量化海岸植物的消浪和透浪特性；植物消浪阻力系数经验公式可以反映植物的物理特性。研究工作可为植物型生态海岸防护工程设计提供科学依据。 |

| As an emerging coastal protection method, plant-based ecological revetments not only fulfill shoreline protection functions but also promote ecological restoration of coastal zones. However, how to scientifically construct plant-based ecological revetments and quantitatively evaluate their wave-dissipating effects remains a challenging issue to be solved. Therefore, two methods, numerical modeling and physical model experiments, were adopted to study this. By incorporating vegetation-fluid interaction terms into the Navier-Stokes equations and adopting the standard Smagorinsky turbulence model to characterize turbulent effects in vegetation-wave interactions, a numerical model was developed by improving the MAC (marker-and-cell method) and wave surface tracking techniques. The numerical model was validated through physical model experiments, and an empirical formula for the vegetation wave dissipation coefficient was constructed. The results show that the constructed numerical model can reflect the wave-dissipation effects of vegetation and quantify the wave-dissipation and wave-transmission characteristics of coastal vegetation, while the empirical formula for the wave dissipation resistance coefficient of plants accurately captures vegetation's physical properties. This research provides a scientific foundation for designing plant-based ecological revetments. |
