摘要

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2 000 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。

Abstract

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, riverbed has been damaged seriously by activities of sand excavation. Regulation actions are proposed in order to improve the channel level in the first-stage of Xiangjiang 2000t channel construction project. The effect of the proposed regulation actions are analysed by using 2-D mathematical flow model and the results indicated that the proposed two design schemes could both meet the design requirements. The right branch scheme is recommended because 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.
