Combined with the instance of practical seawall protection project in Binhai sea area of North Jiangsu province,we explore the wave pressure on wave dissipation platform and seawall structure above the platform under the action of regular and irregular waves in the case of flexible hinged concrete slab mattress revetment and rigid concrete groove block revetment respectively through wave section physical model experiment,and compare the differences between them.The experimental results show that hinged concrete slab mattress revetment does better than concrete groove block revetment in reducing the wave energy and is more conducive to security and stability of seawall.Moreover,corresponding optimization and reinforcement methods for seawall with hinged concrete slab mattress revetment are put forward according to the analytical results of wave pressure.
