摘　　要：丹江口水库调水方案实施后,汉江下游的来水来沙将发生较大的变化,落水期浅滩冲刷流量减小对浅滩影响较大。天然状况下马口滩段上段的浅滩在枯水期得不到较好的冲刷,同时马口弯道的转弯半径较小,目前的航道尺度无法满足设计船队的双向通航要求。分析马口滩段的河床演变特性和碍航特点,针对不同滩段确定了不同的整治原则和整治方法,用物理模型和自航船模试验相结合的方法,提出并研究了满足船舶双向通航的工程方案,可为类似滩段的整治提供参考依据。After the implementation of Danjiangkou water diversion scheme, the coming water and sand in the lower Hanjiang river will change a lot, and the shoal will be influenced greatly due to the reduction of scouring during the drop period. Under natural conditions, the shoal can＇t be scoured well in the dry season, and the small size of the turning radius can＇t meet the bidirectional navigation requirements of the design fleets. This paper analyzes the river bed evolution characteristics and navigation obstruction features, and determines different regulation principles and regulation methods for different shoals. Based on the physical model experiment and selfpropelled ship model test, this paper studies the engineering scheme satisfying the ships＇ bidirectional navigation, which may serve as a reference for similar shoal regulation.
