长江中下游圩区联排泵站规模论证

Demonstration of the Scale of Combined Drainage Pump Stations in the Middle and Lower Reaches of the Yangtze River

为确定长江中下游圩区联排泵站最佳规模,采用MIKE11软件建模,模拟陈家圩内陈家圩站、石船站两座泵站在不同规模条件下联排,并对泵站不同规模组合的排涝效率进行对比分析。结果表明,当陈家圩站流量为4.0m^(3)/s、石船站流量为2.0m^(3)/s时两站联排效果最佳,说明MIKE11模型精度满足长江中下游圩区不同联排工况的排涝效益对比分析,可为长江中下游圩区联排泵站规模方案比选提供重要参考。

To determine the optimal scale of the combined drainage pump station in the middle and lower reaches of the Yangtze River,MIKE l1 software was used for modeling.Simulate the combined discharge of two pumping stations,Chenjiawei Station and Shichuan Station,in Chenjiawei under different scale conditions.And compare and analyze the drainage fficiency of different scale combinations of pumping stations.The results show that the best combined drainage effect is achieved when the flow rate at Chenjiawei Station is 4.0 m^(3)/s and the flow rate at Shichuan Station is 2.0 m^(3)/s.Explain that the accuracy of the MIKE 11 model meets the comparative analysis of drainage benefits under different combined drainage conditions in the middle and lower reaches of the Yangtze River.This can provide important reference for the comparison and selection of scale schemes for combined drainage pump stations in the middle and lower reaches of the Y angtze River.
