摘　　要：本试验在同一"装置"结构中,不同进流含沙浓度下,通过改变进流流量的大小,对"装置"中的浑液面升、降进行调控。根据"装置"内泥沙浓度分布的不同,将其分为4个区:清水区、低于进流含沙浓度的非拥挤沉降区、拥挤沉降区、压缩沉降区。分析了浑液面的升降与进流流量之间的关系,得出浑液面的升降规律。根据浑液面升降过程的调控,可求出"装置"在某一进流含沙浓度下的清水出水量。研究结果可以为弄清"装置"水沙分离的物理机理提供理论依据。Through changing the inlet discharge and different sediment concentration of inflow in the same structure of the turbid water hydraulic power separation device, the experimental researches on the ascending-descending of the turbid-water interface between clean water and turbid water are carried on in this paper. There are four zones, i. e. , clean water zone, non-congested sediment zone, congested sediment zone, compressed sediment zone, in the turbid water hydraulic power separation device. The relationship between the ascending-descending of the turbid-water interface is analyzed, and the law of interface ascending-descending is found out. According to the control process of the ascending-descending of the turbid-water interface, the outlet discharge of the discharge at a sediment content of inflow water can be calculated. Its findings can provide the theory basis for the physical mechanism study of separation clear water from turbid water in the device.
