摘要
为了分析梯级泵站水道系统过渡过程 ,通过对比明渠非恒定流基本方程和管道瞬变流方程 ,建立了管、渠非恒定流联合计算的数学模型 ,并探讨了求解该方程组的特征线格式。在考虑输水系统中泵站事故停泵水锤的基础上 ,结合东深供水工程实例进行了计算分析 ,得出了各泵站的流量变化过程以及各出水道不同位置的水位变化过程、不同时刻的水面线。
In order to analyze the transition process of watercourse system of cascade pumping station, mathematical model of pipe and canal inconstant flow combined calculation is established through comparison between open_channel inconstant flow equation and instantaneous_variable pipe flow equation. The characteristic curve format of the equations solution is also discussed. On the basis of considering water hammer of pumping station failure of water conveyance system, by integrating case study of the Dongshen Water Supply Project, the discharge variation process of the pumping stations, the water level variation process of the outflow courses, and the water level of different moments are deduced.
