从非均匀沙受力分析出发 ,将非均匀泥沙起动所受到的附加作用力分为两部分。用滚动平衡方程式建立了能反映非均匀沙不均匀性的起动流速公式。利用天然河流实测资料和水槽实验资料率定计算公式中的系数 ,并用其它天然河流和水槽资料进行了验证。结果表明 ,公式的计算值与天然河流的实测值和水槽实验的实验值符合较好
Based on the analysis of non-uniform sand force analysis, the additional force of non-uniform sediment start-up is divided into two parts. The equation of starting flow rate which can reflect the non-uniform sand heterogeneity is established by rolling equilibrium equation. The coefficients in the formula are calculated by using the measured data of natural rivers and experimental data of sinks, and verified by other natural rivers and sinks. The results show that the calculated values of the formula are in good agreement with the measured values of the natural river and the experiment of the sink
