营田滩位于湘江濠河口至城陵矶河段，为洞庭湖区洪道，具有典型的河湖两相性，浅滩演变规律复杂。近年来本滩段的采砂活动日益增多，对河床的边界破坏很大，通航水流条件受到影响。在湘江2000 t 级航道建设一期工程中，需采取相应的整治措施，以提升航道等级，满足规划要求。针对营田滩河段的具体碍航特性，提出了相应的整治措施，采用平面二维水流数学模型，对整治效果进行了分析论证。结果表明：设计方案满足航道整治规划要求，右汊方案中洪水期航道水流条件不受上、下挖口入汇水流的影响，又有利于地方经济发展，建议右汊方案作为整治工程的推荐方案。

Yingtiantan is located at the segment between Haohekou and Chenglingji.It is a flood channel of Dongting Lake and has typical characteristics of rivers and lakes with complex shoal evolution.In recent years,ri-verbed has been damaged seriously by activities of sand excavation.Regulation actions are proposed in order to im-prove the channel level in the first-stage of Xiangjiang 2000t channel construction project.The effect of the pro-posed regulation actions are analysed by using 2-D mathematical flow model and the results indicated that the pro-posed two design schemes could both meet the design requirements.The right branch scheme is recommended be-cause the flow condition in the channel is not affected by the confluence of the upper and lower stream opening.It could also contribute to local economic development.
