三峡库区支流常年库区航道通航尺度研究

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。

STUDY ON NAVIGATION SCALE OF THE THREE GORGES RESERVOIR TRIBUTARIES

With the implementation of the Changjiang River Economic Belt national strategy and the regional economic development strategy along the Changjiang river, the development of Changjiang river shipping is facing with a great opportunity. The normal operation of the Three Gorges project provides a good environment for shipping development of the Three Gorges reservoir area's tributaries. As a connecting section between the Chongqing the upper Changjiang river shipping center and Wuhan the middle Changjiang river shipping center, to improve the channel capacity and standard has become an urgent need. Systematic verificated the natural conditions and waterway development situation of the Three Gorges reservoir tributaries, analyzed the impact of the Three Gorges project on the tributary waterway conditions and problems, cleared the method of determining the navigation scale, proposed the navigation scale about 14 major tributaries estuary. Lastly, proposed some measures and recommendations, including strengthen the observation analysis and model demonstration, intensify the infrastructure construction and channel regulation, follow-up observe the influences on waterway about the Three Gorges reservoir sediment deposition.
