摘　　要：埋地输油管道非稳态热力研究能为热油管道间歇输送过程中确定停输时间以及再启动等问题提供基础。通过分析埋地热油管道的几何特性建立了有限区域内非稳态热油管道土壤数学模型和边界条件,并使用PHOENICS软件对该数学模型进行求解。模拟结果与工程现象吻合较好。A study of an unsteady transfer heat underground heated pipeline can provide a foundation for the research on determining the time for stopping and restarting transportation in an intermittent underground heahed pipeline. The mathematical model and boundary condition of the temperature field of the soil in a finite region was established by analyzing the geometrical model of the underground heated pipeline. Then it was solved by PHOENICS software. The results of numerical calculation based on PHOENICS coincide well with engineering.
