摘　　要：由于管线较长、沿线地形地势复杂,长距离输水管道工程的管道水力和水锤计算是工程研究的重点与难点。本文以引汉济渭二期工程北干线黄池沟至板桥出水池段为例,对系统起运过程、停运过程、由设计流量运行过渡到最小流量运行、由最小流量运行过渡到设计流量运行,以及一根管按设计流量运行而另一根管零流量的并管运行等不同工况进行了计算。计算结果表明压力管道内正负压力都在允许范围内。The calculation of pipeline hydraulic power and water hammer in long-distance water pipeline project is the key and difficulty of project research because the pipeline is long and the terrain along the line is complex.Hanjiang-to-Weihe Diversion Project Phase II Project north trunk Huangchigou-to-Banqiao outgoing pool section is adopted as an example.The system shipment process,the service process,designed flow operation transition to the minimum flow operation,minimum flow operation transition to the designed flow operation,combined pipe operation of one pipe operation according to designed flow and one pipe operation according to zero flow as well as other working conditions are calculated.The calculation results show that the positive and negative pressures in the pressure pipeline are within the allowable range.
