摘　　要：针对长距离供水工程设计中遇到的水锤防护难题,设计了联合防护措施的解决方案。以瞬变流基本理论为依据搭建了多个防护方案的水力分析模型,进行实例计算,并对比了联合防护方案与单一防护方案的优劣。结果表明,水锤联合防护措施与单一防护措施相比,在保证系统安全运行的同时,能明显减少工程投资,方便后期运行维护,具有更好的可行性和经济性。In the view of the water hammer protection problems in the design of long-distance water supply project, a solution of water hammer joint protection measures was designed. Based on the theory of transient flow, a variety of hydraulic analysis modes are established. Example calculation was carried out, and the advantages and disadvantages of the joint protection and the single protection were compared. The results show that, compared with a single protection measure, water hammer joint protection can significantly reduce project investment while ensuring the safe operation of the system, facilitate subsequent operation and maintenance, and have better feasibility and economy.
