摘　　要：以安徽省颍上县农村供水保障规划项目为实例,对农村规模化供水工程的水锤防护进行分析。首先研究供水管道水锤形成的气囊运动以及相关计算方法,并通过具体工程实例,对非稳定流工况下的水锤进行计算和分析。结果显示,在水锤防护方案中采用组合式防护,水管P-3的最大压力降低160Pa/m;管道P-149的最大压力降低280Pa/m,表明研究提出的水锤防护对管道具有较好的保护效果。This study takes the rural water supply guarantee planning project in Yingshang county,Anhui province as an example,to analyze the water hammer protection of large-scale rural water supply projects.Firstly,study the airbag motion caused by water hammer in water supply pipelines and related calculation methods.Subsequently,through specific engineering examples,the water hammer under unstable flow conditions was calculated and analyzed.The results show that the combination protection method used in the water hammer protection scheme in the study reduced the maximum pressure of P-3 water pipe by 160Pa/m;the maximum pressure of the P-149 pipeline has been reduced by 280Pa/m.The results indicate that the water hammer protection proposed in the study has a good protective effect on pipelines.
