秦岭终南山特长公路隧道洞口气象观测与分析

Meteorological observation at the portal of Qinling super-long highway tunnel

针对秦岭终南山特长公路隧道通风计算中缺少必要的洞口基本气象参数的情况,建立了洞口气象观测站,对其气象参数进行了周期一年的连续现场观测。文章根据观测结果分析了隧道洞口端各气象参数的变化规律,可为多竖井、深埋隧道通风防灾设计提供较为可靠的依据。

A meteorological observation station was set up near the portal of the super - long Qinling tunnel owing to the shortage of climate parameters required for the ventilation design of the tunnel. On - site observation has been carried out continuously for more than a year. The paper analyzed the observed meteorological data and obtained the regularity of the climate changes near the tunnel portal, which provided a reliable basis for the multi - shaft ventilation and hazard prevention design of this deeply - embedded tunnel.
