The results indicate that the breaking wave pressure is distributed exponentially with respect to water depth. An experimental formula was given using the test data. Compared with test data, the calculated breaking wave forces are in good agreement with the test data.展开更多

The methods for the determination of pressure distribution of horizontal forces on vertical wall as well as u-plift forces on the bottom of wall are also given. The comparison between calculated results by this method and samples of real construction are very well.展开更多

The statistic characteristics of standing wave forces on vertical wall are the same as that of incident waves. But for breaking or broken waves, only large waves break, so the statistic characteristics of breaking wave forces are different to that of standing waves or incident waves. Following a series model test of irregular breaking waves on vertical wall the statistic characterisitics of breaking wave fo.rces were analyzed in this paper. It is found by authors that Weibul distribution may be used to express the statistic distribution of breaking wave forces acting on vertical wall. msed on the analysis of model test data, it is indicated in this paper that the shape parameter m in Weibul distribution is a function of and , in which H is the wave height, d1 is the water depth at the toe of vertical wall and d is the water depth in front of the whole structure; and the theoretical value of scale parameter a can be determined from shape parameter m.展开更多
