In-situ Measurement and Analysis of Ground Temperature Field for Road Tunnel in Cold Regions
Based on the cold-region tunnel named Qingshashan in Qinghai province, a one-way and double lane tunnel with disjunctive up and down lines, located in the east of Qinghai-Tibet plateau, 14 sections were set up to observe the ground temperature with resistance method of temperature determination. The distribution characters of the ground temperature versus time and space were studied. It is found that, 1)Ground temperature field is influenced by air temperature, nature wind, geological conditions and seepage of groundwater. 2)Maximum of negative air temperature and maximum frozen depth is not at the same section3) with increasing of depth the ground temperature increases. 4) The temperature gradient of outer tunnel is different from inner tunnel. The obtained conclusions can guide the construction and design of tunnel in cold regions.
