摘　　要：针对大坝大体积混凝土运输过程中的温度回升问题,建立了运输过程中温度回升计算的差分模型。通过对皮带机运输和自卸汽车+缆机吊罐运输2种不同运输方式分别进行实例分析,并对其温度回升进行比较,得出2种不同运输方式的适用情形,为大坝大体积混凝土运输方式的选择提供了参考。In view of the problem of temperature rise during the transportation of mass concrete for the dam,a differential model for the calculation of temperature rise during the transportation is established.Based on the analysis of two different modes of transportation,i.e.belt conveyor transportation and dump truck+cable crane hanging cage transportation,and the comparison of their temperature rise,the applicability of two different modes of transportation is obtained,which provides a reference for the selection of mass concrete transportation mode of the dam.
