Abstract
基于系列室内水槽冲刷试验,定量研究了在9°坡度、不同流量条件下含沙量对坡面流水动力学参数的影响。结果表明:随含沙量增加,水流雷诺数Re减小,水流紊动强度减弱。弗劳德数、水流流速及流速修正系数α随含沙量增加先呈减小趋势,当含沙量S>300 kg/m3时,各值均突然增大,并随含沙量的进一步增加趋于稳定,表明此时水流型态发生变化,α均值为0.554。含沙水流和清水水流能量损失比较标准不同,得到的结论也不相同。当S<300 kg/m3时,以相同Re或相同单宽流量作为比较标准,含沙水流阻力系数均大于清水对应值;当S>300 kg/m3时,以相同的Re作为比较标准,则含沙水流阻力系数小于清水对应值,以相同的单宽流量作为比较标准,则含沙水流阻力系数大于清水对应值</span
