摘要
基于紊流模型,建立悬移质消耗的紊动动能与水流功率之间的相关关系,提出了一个新的悬移质挟沙力公式。公式经过实验资料与野外资料的验证,并与几个同类公式的比较,结果表明本文公式能更好的反应悬移质挟沙力随水流功率的变化。
Based on Turbulence model,the relationship between the kinetic energy of turbulence consumed by sediment suspension and the power of water flow was established and a modified formula of transport capacity for suspended sediment was thus presented.The modified formula has been calibrated and verified by experiment data and field data and compared with other similar formulae.Results show that the formula can describe the variation of transport capacity with the power of water flow.
