摘　　要：长距离输水工程在管道非正常运行的水力过渡过程中常常会产生水锤现象,危害极大,但对其防护的措施往往只有安装普通排气阀。本文结合宝鸡市某实际工程案例,对长距离重力流和水泵加压联合输水管线的水锤现象及防护效果进行模拟,并给出缓冲排气阀与双向调压塔相结合的安全水锤防护建议。Water hammer was often produced in long distance water supply transmission during the hydraulic transients in pipe system. It was very harmful for the pipeline, but the control measures were usually by exhaust valves only. Combining with the actual project cases in the Baoji City, a computer simulation was performed on water hammer and control effect combined long distance water transmission pipeline of gravity and pump pressure flow. The advices for water hammer control with buffer exhaust valve and two-way surge tank were given here.
