| 摘 要： | 在建立埋地输油管道周围土壤温度场的物理模型时,大多认为温度分布是关于管道中心对称的,因此只考虑对称的一侧,且都为二维计算,简体化了很多方面,这样的考虑是不精确的。结合横向,纵向建立了三维运算模型,使土壤温度场的模拟更接近现实,模拟的结果更加精确。

| Abstract: | When establishing the physical model of soil temperature field around buried oil pipeline,it is mostly considered that temperature distribution is symmetrical on the pipe center,so many factors is usually simplified and computing model is two-dimensional,which will result in errors during establishing the physical model.In this paper,a three-dimensional computing model was established,so the simulation of the soil temperature field was closerto reality,and the simulation result was more precise. |
