In order to deal with the serious problem of siltation in the main channel of the Yellow River Diversion Irrigation Area in Zuncun Village, Shanxi Province, a field water and sediment test was carried out on the main channel. The distribution law of suspended sediment in the channel, the relationship between channel flow and sediment deposition, and the sediment carrying capacity of the channel flow were explored by using the vertical suspension index and the planning solution method, so that it could express the sediment carrying capacity of the flow within a certain range. The critical suspended flow corresponding to the channel particle size was put forward. It was beneficial to prevent siltation by adjusting the flow according to the working conditions and particle size. The sediment carrying capacity formula was optimized. The conclusions are as follows: When the diversion flow is 4.46-24.52 m3/s, the sediment content in the channel is between 0.9-4.0 kg/m3, and the sediment content is positively correlated with the flow velocity. The channel flow can be properly adjusted to more than 39.6 m3/s to effectively suspend the sediment with large particle size. The correlation between the optimized sediment carrying capacity formula and the measured value of the main channel sediment reaches 0.828, which indicates that this formula can reflect the current sediment concentration to a high degree, and provide support for the design and analysis of the balance of channel erosion and deposition in the later stage.

为处理山西尊村引黄灌区干渠淤积严重的问题,对一干渠做实地水沙试验,运用垂线悬浮指标、规划求解方法探究渠道中悬移质泥沙分布规律、渠道流量与泥沙淤积关系以及渠道水流挟沙能力,使其能够在一定范围内表达出水流的挟沙状况。并提出了渠道粒径所对应的临界悬浮流量,根据工况与粒径大小调整流量益于防淤;优化了水流挟沙力公式。结果表明,引水流量在4.46~24.52 m3/s时,渠道泥沙含量在0.9~4.0 kg/m3之间,泥沙含量与流速大小呈正相关;渠道流量调整至39.6 m3/s以上可使渠道内大粒径泥沙有效悬浮;优化后的挟沙力公式针对干渠泥沙计算值与实测值相关性达0.828,说明此公式能够较高程度地反映当前含沙量,为后期渠道冲淤平衡设计与分析提供支撑。

为处理山西尊村引黄灌区干渠淤积严重的问题,对一干渠做实地水沙试验,运用垂线悬浮指标、规划求解方法探究渠道中悬移质泥沙分布规律、渠道流量与泥沙淤积关系以及渠道水流挟沙能力,使其能够在一定范围内表达出水流的挟沙状况。并提出了渠道粒径所对应的临界悬浮流量,根据工况与粒径大小调整流量益于防淤;优化了水流挟沙力公式。结果表明,引水流量在4.46~24.52 m3/s时,渠道泥沙含量在0.9~4.0 kg/m3之间,泥沙含量与流速大小呈正相关;渠道流量调整至39.6 m3/s以上可使渠道内大粒径泥沙有效悬浮;优化后的挟沙力公式针对干渠泥沙计算值与实测值相关性达0.828,说明此公式能够较高程度地反映当前含沙量,为后期渠道冲淤平衡设计与分析提供支撑。

In order to deal with the serious problem of siltation in the main channel of the Yellow River Diversion Irrigation Area in Zuncun Village, Shanxi Province, a field water and sediment test was carried out on the main channel. The distribution law of suspended sediment in the channel, the relationship between channel flow and sediment deposition, and the sediment carrying capacity of the channel flow were explored by using the vertical suspension index and the planning solution method, so that it could express the sediment carrying capacity of the flow within a certain range. The critical suspended flow corresponding to the channel particle size was put forward. It was beneficial to prevent siltation by adjusting the flow according to the working conditions and particle size. The sediment carrying capacity formula was optimized. The conclusions are as follows: When the diversion flow is 4.46-24.52 m3/s, the sediment content in the channel is between 0.9-4.0 kg/m3, and the sediment content is positively correlated with the flow velocity. The channel flow can be properly adjusted to more than 39.6 m3/s to effectively suspend the sediment with large particle size. The correlation between the optimized sediment carrying capacity formula and the measured value of the main channel sediment reaches 0.828, which indicates that this formula can reflect the current sediment concentration to a high degree, and provide support for the design and analysis of the balance of channel erosion and deposition in the later stage.
