| 摘 要： | 采用野外放水冲刷实验的方法,对扰动地面产流产沙规律进行了研究。结果表明:(1)平均产流时间和平均产流量均与坡度不相关,平均产流时间与放水流量呈幂函数关系,平均产流量与放水流量呈二次函数关系。(2)当放水流量为10 L.min-1时,产沙量与坡度呈线性关系,其它放水流量下,产沙量与坡度均呈对数关系;坡度为5°时,产沙量与放水流量呈幂函数关系,坡度为10°和18°时,呈线性关系,产沙量与径流量呈对数函数关系,放水流量是影响产沙量的主要因素。(3)产沙率随放水时间呈减小趋势,大约在前6 min内,产沙率呈增大趋势,达到一个峰值后迅速减小(6~15 min内)。 |

| Abstract: | Laws of water runoff and sediment yield on the disturbed lands resulted from the exploitation of Shenfudongsheng Coalfield were investigated by using field water discharge scouring experiment.The results were follows.(1)No correlations were fould between degrees of slope and average water runoff time and amount.A power function relations existed between the average water runoff time and flow discharge(t=20.18Q-0.571,R2=0.84),second-order relationship existed between the average water runoff amount and flow ... |
