| 摘 要： | 根据温度场的控制微分方程及有限元公式,以吐库二线中天山隧道为例,通过理论计算及数值模拟分析,分别得到在同样的时间周期内相同气温变化对隧道调温圈大小的影响,通过对比发现：计算结果基本一致,可作为后期继续深入研究的基础依据.

| Abstract: | Using the control differential equations and the finite element formula of temperature field, this paper compares the influences on the scale of thermal control loop calculated by theoretical arithmetic and numerical simulation analysis in the condition of same time and atmospheric temperature. Taking Zhongtianshan Tunnel of Tu-Ku second line as an example, it can be concluded that the theoretical result are basically in agreement with the analysis one, and the concequences can be used as basis in further research. |
