摘　　要：冬奥会延庆赛区造雪引水及集中供水工程具有小流量、长距离、高扬程、纵坡大等特点,造成水力过渡过程不同于常规工程的计算特征,依据计算,叙述和分析了空气阀布置方案及空气阀、泄压阀等防水锤设备选择的特点.对长距离、高扬程输水系统的过渡过程计算与水锤防护设备的选择具有一定的借鉴作用.Snowmaking water diversion project for Yanqing area of Beijing 2020 Winter Olympic Games has the characteristics of small flow,long distance,high lift and large longitudinal slope,which makes the characteristics of hydraulic transition process different from conventional engineering.based on the hydraulic transient process calculation,the paper describes and analyzes the air valve layout scheme and the selection of water hammer protection equipment such as air valve and pressure relief valve.It can be used for reference to the calculation of the hydraulic transition process of long-distance and high-lift water conveyance system and the selection of water hammer protection equipment.
