摘要: 为探究寒区隧道纵向温度场分布规律及其影响要素,以哈牡高速铁路鲜丰隧道工程为例,建立寒区隧道三维流固热耦合模型,并采用通风时间、等效自然风流速度及进洞风温3个变量,探究不同变量条件下寒区隧道纵向温度分布规律及变化特点,在此基础上提出寒区隧道洞内纵向温度预测公式。研究结果表示: 1)寒区隧道洞内纵向温度随着进洞距离的增加呈先上升后下降的趋势; 2)随着通风时间的增加,寒区隧道洞内各个断面温度逐渐降低,且在通风60 d左右逐渐趋于稳定; 3)随着等效自然风流速度的增大,隧道内纵向温度会降低; 4)进洞风温对隧道洞内温度场的分布具有直接影响,随着进洞距离的增加,进洞风温对洞内温度场的影响逐渐减小。

Abstract: To investigate the longitudinal temperature field distribution patterns and influencing factors of tunnels located in cold areas, a case study is conducted on the Xianfeng tunnel of the HarbinMudanjiang highspeed railway, and a threedimensional fluidsolid thermal coupling model is established for cold area tunnels. Variables such as ventilation time, equivalent wind speed, and wind temperature are used to investigate the longitudinal temperature distribution trends and variations in these tunnels. Ultimately, a calculation formula for the longitudinal tunnel temperature in cold area tunnels is derived. The main conclusions can be summarized as follows: (1) The temperature inside the tunnel increases and then decreases as one moves further. (2) The temperature in each tunnel section in the cold area gradually decreases with increasing ventilation time, eventually stabilizing after 60 days of ventilation. (3) KG-*9〗〖JP3The temperature in the longitudinalJP direction of the tunnel decreases with increasing equivalent wind speed. (4) The inlet wind temperature directly impacts the tunnels temperature field, but its influence weakens as one moves further into the tunnel.
