| 摘 要： | 近期得到的高、中、低浓度挟沙水流统一挟沙力公式均以能量平衡为基础，公式都反映出紊动扩散作用与重力作用之比是决定挟沙力大小的最关键因素．利用实测的１８０ 多组资料对这些公式进行对比、验证，并对阻力系数的确定进行分析

| Abstract: | Based on the energetic balance, several formulae of sediment carrying capacity for sediment laden flow with high, median and low concentrations have been constructed recently. In this paper, more than 180 groups of field observed data have been used to contrast and verify these formulae. Meanwhile, a right method to determine the resistance coefficient has been carried out. |
