本文基于巴家嘴水库1964年汛后—1968年汛后、1973年汛后—1979年水库泄空运用的两个阶段,引出了“滩面河槽”的概念,对其形成、演变过程,作了定性描述;对河槽末端的溯源速度与入库流量的关系,作了定量分析;探求了滩面河槽相对稳定的河相关系和决定滩面河槽规模的滩槽高差、横断面边坡角度与距坝里程之间的相应数量关系。
Based on the two stages of the reservoir discharge in the Bazijiai Reservoir after the flood season in 1964, the flood in 1968, the flood season in the late 1973, and the reservoir in 1979, the concept of “tidal flat on the beach” is brought forward, and its formation and evolution process The relationship between the trace velocity at the end of the river channel and the inflow rate was quantitatively analyzed; the relatively stable river-river relationship of the river channel was explored; the difference between the channel height and the slope angle of the cross-section slope The corresponding number of miles between the dam mileage.
