摘　　要：发展新型护坡结构对提高海堤工程结构强度,降低失事风险具有重要意义。为得到一种新型海堤护坡结构的更加准确的试验数据,基于Flow-3D软件对双曲弧面海堤护坡结构进行水动力数值模拟试验,并从消能防潮效果和压强分布特征等角度与传统海堤护坡结构进行对比分析。计算结果进一步验证了新型海堤护坡结构的导流消能效果,证明其能在中、高流速涌浪冲击下有效提高越浪高度,形成较好的潮涌景观效果,同时还明晰了新型双曲海堤护坡的结构安全薄弱区域。研究成果为复杂水流条件下新型海堤护坡结构的应用及推广提供了理论及数据支撑。Developing new revetment structures is crucial for enhancing the structural strength of seawalls and reducing the risk of failure.For obtaining more precise experimental data on a novel type of seawall revetment structure,we conducted hydrodynamic numerical simulations of the hyperbolic arc seawall revetment structure using Flow-3D software.We then compared its energy dissipation and wave protection effectiveness,as well as pressure distribution characteristics,with traditional seawall revetment structures.The computational results further validated the new seawall revetment structure's flow-guiding and energy dissipation effects,demonstrating its ability to effectively increase wave overtopping height under medium and high flow velocity surge impacts,creating a better surge landscape effect.The study also identified the structural safety weak points of the new hyperbolic seawall revetment.The findings provide theoretical and data support for the application and promotion of the new seawall revetment structure under complex flow conditions.
