摘　　要：由于地形地质条件限制,长距离高扬程多起伏输水管道易发生水锤事故,水锤防护较难。针对上述问题,本文介绍了长距离高扬程多起伏输水系统的水锤防护措施及箱式双向调压塔的工作原理,并结合具体工程案例,通过计算机软件分析了有压管道在非正常关闭时的水锤压力波动,比较了多种设备组合使用的水锤防护效果。实践证明,运用箱式双向调压塔对保护输水管道有着重要作用。Due to the limitation of the topographical and geological conditions, the water hammer accident happened easily in water pipeline with long distance, high-lift and multi-fluctuation. The control of water hammer was difficult. The control measures of water hammer were introduced amied at the above issues, as well as the working principle of box-type two-way surge tank. Combined with a specific engineering case, the pressure fluctuation of water hammer was analyzed in pressurized pipeline under the abnormal closing condition by computer software, and the control effects of water hammer were compared by combined use of different devices. The practice proved that the box-type two-way surge tank played an important role in protecting water pipeline.
