晋江滨海新区护岸越浪量试验

Study on Wave Overtopping at Revetment

通过物理模型试验,对斜坡式护岸及其断面在不规则波作用下的越浪量进行观测,分析波向角θ对越浪量的影响规律。结果表明,当相对波高H_c/H_s<1.0,θ>20°时,随着θ的增大,越浪量明显减小。将典型公式计算的越浪量结果与物理模型试验结果进行对比。结果表明,对于0.01~0.1 m^3/(m·s)范围内斜坡堤的越浪量,《海港水文规范》与Van der Meer的计算结果较物理模型偏差较大,陈国平公式计算结果与物理模型较吻合。

Based on the physical model experiments,this paper carries out a research on the wave overtopping at oblique revetment with the irregular wave. The influence of the wave direction angle（ θ） on the wave overtopping is analyzed.The results show that wave overtopping volume decreases significantly with the increase of the wave direction angle when the relative height（ H_c/ H_s） 1 and θ 20°. Besides,this paper compares the results calculated by the existing formulas about the overtopping volume with the physical model experiments. Within 0. 01 ~ 0. 1 m^3/（ m / s） overtopping volume,the calculation results of Van der Meer and ＂ Seaport Hydrology Standard＂ are larger than the physical model experiments. Meanwhile,Chen Guo-ping＇s results are coincident with the physical model experiments relatively.
