摘要: 高原区螺旋隧道受低气压、空气稀薄及曲线半径等因素的影响,隧道内CO运移规律不同于常规隧道。以卧龙沟1号隧道工程为依托,利用Fluent软件模拟分析,通过将高原区螺旋隧道与常规隧道进行对比分析,得到高原区螺旋隧道内CO浓度场的空间分布规律和分布特点,同时结合现场监测数据验证了结果的可靠性。并得到各海拔高度下R=700 m的螺旋隧道的通风安全时间相对常规隧道的增长率,该参数可作为隧道通风的参考依据;根据计算结果提出了高原区螺旋隧道通风管理的相关措施。

Abstract: The plateau spiral tunnel is affected by factors such as low air pressure, thin air and curve radius. The CO transport law in the spiral tunnel is different from that in the conventional tunnel. Based on the Wolonggou No. 1 tunnel project, the Fluent software was used to simulate and analyze, and the spatial distribution law and distribution characteristics of the CO concentration field in the spiral tunnel of the plateau area were obtained by the comparative analysis of the plateau spiral tunnel with the conventional tunnel. Meanwhile, the reliability of the results was verified by combining with the monitoring data of site. And the increase rate of ventilation safety time of the spiral tunnel with R=700m at each altitude compared with that of conventional tunnel was obtained, which can be used as reference basis for tunnel ventilation. According to the calculation results, the relevant measures for the ventilation management of the spiral tunnel in the plateau area were proposed.
