| 摘 要： | 通过现象分析，在黄河小北干流河段小流量(1220m^3／s-4600m^3／s)和持续高含沙量(500kg／m^3-790kg／m^3)的情况下也可产生局部揭河底冲刷。小北干流河段河床已经具备了揭河底的边界条件，如果水沙条件具备，很可能再次发生“揭河底”。

| Abstract: | Through the analysis of phenomena, this paper presents the conditions under which the "bottom tearing scour"may occur in Xiaobeigan Main Stream of the Yellow River: the discharge of Yellow River is from 1 220 m3/s to 4 600 m3/s,and the sustainable silt concentration is from 500 kg/m3 to 790 kg/m3 meanwhile. Xiaobeigan Main Stream has be possessed of boundary condition of river bed for "bottom tearing scour"now. There is huge possibility to form this scour again. |
