Abstract

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.

Key words
