摘要
为研究长江下游感潮河段某支流泵站排涝对下游自来水厂取水口的影响,分别采用数学模型和物理模型进行模拟。结果表明:受感潮河段潮汐水动力条件影响,排涝水体对取水口的影响呈现明显的两涨两落规律。数学模型模拟结果显示,长江流量为45000 m^(3)/s时,泵站流量14 m^(3)/s对取水口无影响。泵站流量为35 m^(3)/s时,对取水口的影响随长江流量减小而增大。物理模型模拟结果显示,长江流量为45000 m^(3)/s时,泵站流量7 m^(3)/s对取水口无影响。泵站流量为21 m^(3)/s时,泵站排涝对取水口的影响呈长江流量45000 m^(3)/s>30400 m^(3)/s>62000 m^(3)/s。2类模型相辅相成,作为一种新的研究手段,将是今后发展的重要方向。
Mathematical and physical model were used to study the influence of pumping station drainage on downstream water plant in tidal reach of the Yangtze River.The simulation results of mathematical model and physical model showed that affected by the tidal hydrodynamic conditions of tidal reach,the influence of drainage water body on water intake showed an obvious regular pattern of two rises and two falls.The simulation results of the mathematical model showed that when the flow of the Yangtze River was 45000 m^(3)/s,14 m^(3)/s flow of the pump station had no impact on the water intake.When the flow of the pump station is 35 m^(3)/s,the impact on the water intake increased with the decrease of the flow of the Yangtze River.The simulation results of physical model showed that when the flow of the Yangtze River was 45000 m^(3)/s,the flow of the pump station was 7 m^(3)/s,which had no impact on the water intake.When the flow of the pump station was 21 m^(3)/s,the impact of the drainage of the pump station on the water intake showed as 45000 m^(3)/s>30400 m^(3)/s>62000 m^(3)/s of the Yangtze River's flow.As a new research method,two kinds of hybrid models will be an important direction in the future.
