随着长江经济带国家战略及沿江区域经济发展战略的实施,长江航运发展面临重大机遇。三峡水库的运行为三峡库区众多支流的航运发展提供了良好环境,作为连接重庆、武汉两大区域航运中心的连接段,库区干支航道的能力提升和标准提高显得尤为迫切。系统核查了三峡库区支流自然条件及航道发展现状,分析了三峡蓄水对支流航道条件的影响及蓄水后库区支流航道存在的问题,依据现有标准规范明确的航道尺度确定方法,论证提出了三峡库区15条主要通航支流河口段航道的通航尺度。最后,提出了加强观测分析与模型论证,加大基础设施建设与航道治理力度,以及跟踪观测三峡库区泥沙累积性淤积对航道的影响等建议。
With the implementation of the national strategy of the Yangtze River Economic Belt and the economic development strategy along the Yangtze River, the development of the Yangtze River shipping faces significant opportunities. The operation of the Three Gorges Reservoir has provided a good environment for the development of many tributaries of the Three Gorges Reservoir. As a connecting section connecting shipping centers in Chongqing and Wuhan, it is particularly urgent for the capacity of the branch and branch channels in the reservoir area to improve and standardize. The tributary of the Three Gorges area was systematically checked for its natural conditions and the status quo of waterway development. The influence of the Three Gorges reservoir on the tributary waterway conditions and the problems existing in the tributary waterway after the water storage were analyzed. According to the existing criteria, Proposed the navigable standard of 15 major navigable tributaries estuary channel in the Three Gorges reservoir area. Finally, suggestions are put forward to strengthen the observation and analysis of the model, increase the intensity of infrastructural construction and waterway regulation, and follow-up observation of the sediment accumulation in the Three Gorges reservoir area on the waterway.
