摘　　要：本文通过水槽试验资料，分析了影响螺旋流排沙管泄流量的主要因素，提出螺旋流排沙管泄流量计算公式，并经三座水电站排沙管泄流量原型观测验证，用该公式计算排沙管泄流量筒便可靠、精度较高，可供设计排沙管时参考。In this paper, using the data of flume experiments, the maineffects on flow discharge in sedimena washing twbe with spiral current are studied. The calculating formula of the discharge is made out and is verified with yield date of three water-power staions. The formula is of simple, reliable and exact. It can be consulted in planing of the Scour tubes.
