摘　　要：本文对杨国录分组水流挟沙力公式的合理性进行了分析,利用黄河下游2380组实测资料,对公式中的某些重要参数进行了率定,并进行了验证计算,结果表明:该公式综合考虑了各种水力因子对水流挟沙能力的影响,能较好的反映一般含沙量及高含沙水流的输沙能力,且分组水流挟沙力也比较符合黄河的实际情况。This paper analyses the reasonability of the force formula of Yangguolu current holding sand,and the some key parameters are checked and validation calculated using 2380 group survey data.The result indicates that the formula can preferably reflect the conveying sand capacity for the currently and highly holding sand,and the force also relatively accords with the fact situation of Huang River,because the formula synthetically consider the influence of the current holding sand capacity caused by all kinds of water power factors.
