摘　　要：在考虑了恒温层及大气温度年周期变化影响的基础上,分别给出不同敷设方式下热油管道稳定运行时热力计算数学模型,介绍了验证的方法,测试管道首末站温度进行模型验证。通过模拟计算数据与测试数据的对比,误差均小于3%,满足工程要求,证明了模型正确。On the base of taking the influence from the constant temperature of the earth＇s layer and air cyclic variation in year into account,the thermal calculation mathematics models of hot pipeline steady operation in different laying way were established and the test way was introduced,which were verified to be right by the temperature at inlet and outlet of heating stations.By being compared experiment data with test data,all the errors are below 3%,which can meet the demand of project and verify the models to be right.

关 键 词：稳定运行 热力计算 数学模型 验证
