摘　　要：长江南京以下12.5 m深水航道二期工程建设是落实国家"一带一路"战略、打造长江综合立体交通走廊的重大举措。针对二期工程河段4个水道的碍航情况,在分析上游来流来沙特性、各水道分流分沙特性及演化过程的基础上,对碍航特性、河床演变特性及趋势进行分析,提出各水道的整治时机、关键部位和治理思路。成果为航道整治工程设计与建设提供技术支撑,也为感潮河段航道整治积累经验。The deep-water channel phase II project plays a significant role in the Belt and Road Initiative and is an important part of comprehensive three-dimensional transport corridors in the Yangtze River economic belt.Mainly for the four reaches which have navigation obstruction we analyze the characteristics of hydrology-sediment upstream the flow-sediment distribution and the river evolution process also study the features of navigation obstruction and the trends of river bed revolution.Afterwards we propose regulation occasion and key locations of each water reach as well as the thinking of navigation regulation project.The results offer technical support for the design and construction of channel regulation programs and provide good experiences for channel regulation of tidal rivers.
