摘　　要：航道整治需抓住工程实施的有利时机,在通航条件还未恶化前提前预防。以淮河出海航道(红山头—京杭运河段)大淤滩整治工程为例,利用平面二维水流数学模型对滩头不同侵蚀方案产生效果进行计算,分析若不对滩头进行守护将可能导致的后果,说明滩头守护的必要性,并结合河床演变分析提出滩头整治工程平面布置方案。The channel regulation should be implemented at appropriate time before the navigation condition is deteriorated. Taking the regulation of the Dayu beach in the Huaihe outfall waterway （ 1-Iongshantou to the Grand Canal section） as an example, various erosion schemes of the head of Dayu beach are calculated by a two- dimensional flow model. The consequences without protection at the head of the beach are analyzed which explains the necessity of protection. At last, combining with the recent river evolution, a beach regulation layout plan is proposed. This method may serve as reference for the decision-making of the regulation plan.
