摘要: 为分析导流护滩带效果,以长江中游荆江太平口水道腊林洲低滩守护工程为背景,采用概化模型试验,分析了护滩带对河床的影响。结果表明,实施后的护滩带守护工程,起到了良好的护滩作用,腊林洲低滩的稳定性有所保障,并且滩体中段适当恢复,产生了较好的导流效果,强化了“南槽—北汊”的水流衔接形式,促进了太平口水道出口至三八滩段航道条件的改善。研究结果为太平口水道航道整治工程建设方案提供了技术支撑。

Abstract: Generalized model test was performed to study the effect of beach protection belt at Lalin sandbar in Taipingkou waterway of Jingjiang River in the middle Yangtze River. Result demonstrates that the beach protection belt project plays a good role in flow control and enhances the stability of Lalin sandbar. The project restores the middle segment of the Lalin sandbar, giving rise to a good flow diversion effect and intensifying the flow connection from the south trough to the north branch, and therefore ameliorates the navigation channel from the outlet of Taipingkou to Sanba sandbar. The research result offers technical support for the navigation channel regulation project at Taipingkou waterway.

Key words: middle Yangtze River, Taipingkou waterway, low beach protection project, generalized model, stability of beach protection belt
