秦岭特长多竖井深埋隧道气温测试研究

Temperature measurement in the extra-long and deeply- embedded Qinling tunnel with many shafts

文章依托秦岭终南山特长隧道 ,对隧道洞室内外气温、风速等气候条件进行了现场测试 ;研究隧道位置地层温度、洞内风速变化、外界气温变化等因素影响下 ,隧道内自然风速及洞内气温的变化范围和变化规律 。

The paper studies the extent and regularity of the variation of temperature inside the tunnel under the influence of ground temperature, variation of inside wind speed and outside temperature based on the in situ measurement of the climate conditions inside and outside the Qinling extra long tunnel, which provides the basis for the design of the ventilation and disaster prevention for the deeply embedded tunnels with a lot of shafts.
