Experimental Study on Air Temperature Field for Cold-Region Tunnel in Qinghai-Tibet Plateau:A Case Study

摘要

In order to reveal the temperature distribution of the tunnels in cold region, a typical cross-section was chosen and the systematic measurement and analysis were carried out weekly for the temperature field inside and outside the tunnel-hole by using hygrometer, taking the Qing Shashan highway tunnel in the east of Qinghai-Tibet Plateau as the backing, The results provide basis for antifreeze insulation and operating ventilation design, and also provide reference for related research of the similar tunnel projects.
