| Summary: | 碩士 === 國立中興大學 === 土木工程學系 === 88 === Estimating the quantity of wave overtopping is an essential part to seawall design. Most previous studies were only paid attention to the volume rate of wave overtopping. This paper investigated the effect of wave overtopping on the property of wave pressure on the composite breakwater by means of model experiments. This irregular wave type was Bretschneider-spectrum. Wave pressure was measured on the face of the breakwater at vertical and upright section. Through Kolmogorov-Smirnov goodness-of-fit to test experimental data, it reveals that Weibull function is a more suitable function to describe the probability distribution of wave pressure where still water level than log-normal and Rayleigh function. It was found from the experimental results that the wave pressure on the breakwater was reduced due to the wave overtopping, which was depended on the incident wave condition and the crest height of the breakwater above the still water level. Regression equation obtained in this study was useful for the water surface elevation and the crest height.
