芦家河浅滩段复杂水流特性及治理思路

Complicated flow characteristic of Lujiahe reach and regulation idea

针对长江中游芦家河水道浅、陡、急的航道问题,对本水道治理思路进行研究。采用三维数学模型分析芦家河水道水流特性,并针对浅滩碍航特性提出初步治理方案。结果表明,通过"疏槽维稳"可同时解决本水道"浅、陡、急"三方面的航道问题。研究成果可为枯水期水浅、流急、坡陡的卵石浅滩治理提供借鉴。

Aiming at the shallow water,steep slope and torrent flow of Lujiahe waterway,we probe into the train of thought on the waterway regulation.Adopting the three-dimensional numerical analysis model,we analyze the flow features and propose a preliminary plan for regulating this waterway.The research results reveal that dredging is the effective method to solve the navigation channel problem,and the research achievement may serve as reference for regulation of the pebble shoal which is characterized by shallow water,torrent flow and steep slope.
