巢湖闸是巢湖的主要出水口,2003年由原来的10孔节制闸扩大为16孔,巢湖闸扩孔建设提高了巢湖洪水的渲泄能力。但是,由于河道清理工作没有与闸门扩建同步进行,致使水流改变了原测沙断面的沙量横向分布,本文就单断沙关系与河床断面之间的关系进行相关分析。
Chaohu Lake is the main outlet of Chaohu Lake. In 2003, it expanded from 10 holes to 16 holes, and reaming at Chaohu Gate increased the flood release capacity of Chaohu Lake. However, since the river channel cleaning work is not carried out in parallel with the expansion of the gate, the water flow changes the horizontal distribution of the sand mass at the original sand measurement section. Correlation analysis is made between the single-break sand relationship and the riverbed section.
