长江中游鲤鱼山水道治理思路与方案

为给长江中游鲤鱼山水道航道治理提供技术支撑,开展水道治理思路及方案研究。通过鲤鱼山水道近期航道变化及存在问题研究,提出"以北槽为通航主槽,通过工程稳定滩槽格局,抑制南槽发展,适当改善北槽航道条件"的治理思路,并借助河工模型提出航道治理总体方案,该方案可以达到河段2020年规划航道尺度。

Regulation idea and scheme of Liyushan in the middle Yangtze River

To provide a technical support for the regulation work of Liyushan waterway in the mid-reach of the Yangtze River,we research the regulation principles and implementation schemes.Based on the analysis of the recent navigational conditions of Liyushan waterway and its negative evolution tendency,we propose the regulation principles,i.e.,taking the north channel as the main navigation channel,to stabilize the current river regime and channel-shoal layout by protective engineering,control the development of the south channel and improve the navigation condition of the north channel.With the help of physical model tests,we recommend the general regulation scheme for the waterway regulation,which ensures to satisfy the planned channel dimensions of year 2020.
