摘要
太湖流域水流运动复杂,摸清太湖上游地区来水情况,对于保障太湖水安全具有十分重要的现实意义。通过数值模拟的方法,研究了太湖上游区和长江、太湖的水量交换特征及水流运动特性。结果显示,在现有水利工程调度运行下,湖西区总体以入太湖和入武澄锡虞区为主,但京杭运河以南部分河道常年倒流,同时,无锡城区调水引流和梅梁湖泵站引水抬高了运河无锡站水位,导致运河向东泄水不畅,水流向南并倒流入湖西区,最终进入太湖。
In order to search the water movement law in the upper reaches of Taihu Lake,this research takes Huxi District and Wuchengxiyu District as research objects,uses numerical simulation methods to study the effects of different water and rain conditions on water exchange characteristics and flow movement characteristics between the two regions,the Yangtze River,and Taihu Lake.The results show that under the existing water conservancy project dispatching operation,Huxi District is generally dominated by the Taihu Lake and Wuchengxiyu District,but the two rivers in the south of the Grand Canalin show that Wuchengxiyu District's water flows into Huxi District.At the same time,the water diversion project in Wuxi urban area and the pumping of the Meiliang Lake pumping station have raised the water level of the Grand Canal at Wuxi Station,causing the Grand Canal to leak to the east,and the upstream section of Luoshe is also supported to some extent.
