一种新型双曲弧面海堤护坡结构的防浪消能效果

Wave Prevention and Energy Dissipation Effect of a New Type of Seawall Revetment Structure with Hyperbolic Arc Surface

研发新型海堤护坡结构对守护人民生命安全、提高海堤工程稳定性具有重要意义。针对钱塘江河口潮流强劲,而传统海堤护面光滑,难以对强大冲击浪进行有效缓冲的工程问题,设计研发了一种具有双曲弧面结构的海堤护坡结构,采用室内水力试验和数值模拟等手段对其防浪效果、压强分布特征进行分析。研究结果表明,新型海堤护面结构通过有效引导、改变冲击浪的流向及流态,既能起到较好的消能作用,又能增强钱塘江大潮的观景效果,为复杂水流条件下海堤护坡结构设计提供了新的工程思路。

Developing new types of seawall revetment holds significant importance in safeguarding lives and enhancing the stability of seawall projects.To address the challenge of ineffective buffering of strong shock waves caused by the swift current in the Qiantang River estuary and the smooth surface of traditional seawalls,we have devised a seawall revetment structure with hyperbolic arc surface.Through indoor hydraulic testing and numerical simulation,we examined the wave dissipation effect and pressure distribution characteristics of the structure.Findings demonstrate that the new seawall revetment structure not only improves energy dissipation by guiding and altering the pattern and direction of impact wave flow,but also enhances the aesthetic appeal of the Qiantang River tide.This approach presents a novel engineering concept for designing seawall revetment structures in complex water flow conditions.
