中文摘要：

基于三维波浪物理模型实验研究的结果，参照国内外已有的研究成果，探讨了波浪斜向性和多向性对不规则波作用于直墙堤上波浪荷载的影响，表明波浪是否在堤前破碎其影响波浪荷载的规律是不同的。建议了斜向和多向不规则波作用于直墙堤上波浪荷载的实用计算方法。

英文摘要：

Based on the results of a 3-D wave model test and referring to the achievements in literature, the effects of wave obliquity and multi-directionality on wave loads acting on vertical wall are investigated. It is found that the effects of non-breaking wave and breaking wave are different. A practical method for determining the wave loads from oblique and multi-directional irregular waves on vertical wall is recommended.
