六盘山特长高速公路隧道位于宁夏回族自治区南部的隆德和泾源县境内,长约9.5km,属于位于山岭气候分割带的特长公路隧道。隧道设计高程为2074~2230m,各洞口之间高差大,隧道贯通后由于各洞口之间存在温度差及超静压差从而在洞内形成不稳定的自然风流。对贯通后的六盘山隧道洞内自然风进行实测以研究其洞内自然风流大小及变化规律同时实测可为理论及数值计算结果进行验证。
The Liupanshan Expressway Tunnel is located in Longde and Jingyuan County in the south of Ningxia Hui Autonomous Region, about 9.5km long and belongs to a special highway tunnel located in the mountain climate division zone. Tunnel design elevation of 2074 ~ 2230m, the hole between the large difference between the large tunnel after the tunnel due to the existence of the temperature difference between the hole and the ultra-static pressure difference in the cave to form an unstable natural romantic. The measured natural wind in the tunnel through the Liupanshan Tunnel to study the size and variation of the natural wind flow in the tunnel at the same time can be verified by theoretical and numerical results.
