波浪斜向入射角对单向不规则波爬高的影响

In this paper the wave runup has been studied. The wave runup influence factors are very complicate, due to various research tools and methods, different scholars get different calculation methods of wave run-up. But most of research has been oriented at perpendicular wave attack, little on obliquely incoming waves which in fact are common in nature. Therefore, an investigation is necessary.The paper carried on an investigation with obliquely incoming waves in the foundation of analyzing and summarizing the results presence. In this paper 3-D Physical model tests about the wave run-up have been performed with irregular waves , considering the effect of the angle of the wave attack. The reduction factor Kβ has been set out against the angle of wave attack β. The results from the test are in accord with the rule of assumed by Guoping Chen.
