摘　　要：过高的防洪堤不仅影响工程投资,而且对环境、交通和景观等造成不利影响。通过分析《堤防工程设计规范》中堤顶高程按允许越浪与不允许越浪设计存在的主要差别,并结合浙江省小流域的实际情况,认为小流域堤防的堤顶高程可按允许越浪进行设计,这样可使堤防的堤顶超高降低28～55 cm,不仅可节约工程投资,同时也较好地解决了防洪与景观的关系问题。可为小流域堤防设计参考。Overhigh flood prevention levee not only needs larger investment,but also has unfavorable impact on environment,traffic and landscape.According to the main design difference between wave allowable overtopping and unallowable overtopping regulated by Code for Design of Levee Project and in the combination of practical condition of Zhejiang Province,it is considered that the levee elevation of a small basin in Zhejiang Province can be designed as allowable overtopping,which can reduce the crest elevation by 28~55 cm,resulting in saving investment and achieving a good relation between flood control and landscape.
