六盘山特长公路隧道长约9.5km,是跨越气候分隔带的特长公路隧道。由于隧道洞口附近气候环境因素差异,隧道内会形成不稳定的自然风流。为研究隧道内自然风流大小及变化规律,在六盘山隧道2主洞洞口、2斜井洞口规划设计并建立起4个自动气象站,对六盘山隧道的2个主洞口及2个斜井出口处进行长期气象监测,并取得了温度、相对湿度、风速、风向和气压等相关因素的长期气象资料。 The Liupanshan Extra-long Highway Tunnel, about 9.5km long, is a specialty highway tunnel that straddles the climate zone. Due to the difference of climatic and environmental factors near the tunnel entrance, unstable natural wind flow will form in the tunnel. In order to study the size and variation of the natural wind flow in the tunnel, four automatic weather stations are planned and designed in 2 main tunnel openings and 2 inclined shaft openings in Liupanshan tunnel. Two main tunnel openings and two inclined shaft outlets Long-term meteorological monitoring, and made the temperature, relative humidity, wind speed, wind direction and pressure and other related long-term weather data.
