摘要
针对枯水期葛洲坝三江吃水受限问题,提出了兼顾三峡枢纽水运新通道建设的葛洲坝三江下引航道扩挖思路及建设方案。综合考虑新通道设计代表船型及三江引航道交通流,分析计算三江引航道尺度需求,研究三江下引航道挖深后对葛洲坝枢纽通过能力的提升程度以及对航运效益影响。工程实施后,葛洲坝枢纽年通过量大约可提高669.8万t,实现直接经济效益3.35亿元/a。
In view of the limited draft of the Gezhouba Dam Sanjiang ship locks during the dry season, this paper puts forward a thought of excavation extension and a development scheme for Gezhouba Dam Sanjiang downstream navigable channels that take into account the construction of the new waterways of the Three Gorges Hydro-junction. Comprehensively considering the representative ship type in the new channel design and the traffic flow in the Sanjiang navigable channels, this paper analyzes and calculates the scale requirements of the Sanjiang navigable channels and investigates the improvement degree of the passing capacity of the Gezhouba Dam Hydro-junction and the impact on navigation benefit after the deepening of the Sanjiang downstream navigable channels. The implementation of the project will increase the annual throughput of the Gezhouba Dam Hydro-junction by approximately 6.698 million t and yield a direct economic benefit of 335 million CNY/a.
