摘　　要：在分析试验资料的基础上，对粗沙异重流的形成条件、运动规律及输沙特性进行了探讨，建立了粗沙高含沙水流的数学模型．用包括粗沙支流在内的实测资料对３个挟沙力公式进行了验证．模型用三门峡水库１９７４年到１９８４年资料进行验证，计算值与实测值吻合较好．Based on the analysis of test data, the formulation conditions of density flow with coarse particles and its flow law as well as its transportation behaviors are discussed. A mathematical model is developed. The model is tested with the data from Sanmenxia in 1974 to 1984 and good agreement is attained.
