摘　　要：建立了埋地盗油管道年周期性变化温度场的物理模型,通过简化该物理模型建立了埋地盗油管道数学模型,进行了数值模拟运算。分析比较了不同月份埋地盗油管道热影响区域地表温度场特征,其结论表明:夏天相同距离温度差异比较小,在冬天相同距离温度差异比较大。The physical model of the annual periodicity the temperature change of buried pipeline was established, and the mathematic model was established according to the simplified physical model for some numerical simulation. Also, the temperature field characteristic of pipes in the area influenced by heat in different months was analyzed. The results indicate that the difference of the same distance is less in summer, and much in winter.
