摘　　要：针对4条典型管道,采用典型浆体管道临界流速和摩阻降计算模型进行计算,通过对比模型计算值与4条管道工程实测值,分析模型的计算精度。结果表明,瓦斯普模型、韩文亮模型、费祥俊模型、刘德忠模型计算的流速和管径值与实测值吻合度高,最大偏差均处于±15%范围内;费祥俊模型在计算摩阻降上具有很高的精度,最大偏差处于±10%范围内,不仅具有较高的计算精度,也具有一定的计算裕量,可为浆体长距离输送提供有力的设计依据和指导。Calculation was made for four typical pipelines by adopting typical critical flow rate and frictional pressure drop calculation model.The precision of the model was analyzed by comparing the calculated value with the measured value of four pipelines.The results show that as for flow rate and pipe diameter,the calculated values from Wasp model,HAN Wenliang model,FEI Xiangjun model and LIU Dezhong model are in good agreement with the measured value,presenting the maximum deviation within the range of±15%.FEI Junxiang model presents higher precision in the calculation of frictional pressure drop,with the maximum deviation within the range of±10%,but also has certain margin in calculation.It is concluded that FEI Xiangjun model can provide an important basis and reference for the design of long⁃distance transportation.
