若多雪地区隧道洞口附近处理措施不当,一方面风吹雪及积雪会造成隧道洞口积雪堵塞,中断交通;另一方面风吹雪将阻挡和模糊视线,积雪融化后路面结冰,极易发生交通事故。以G045线赛里木湖至果子沟口改建工程隧道洞口防风雪设计为例,对多雪地区隧道洞口采用数值模拟方法进行了分析研究,为确定隧道洞口方案提供了依据,较好地解决了隧道洞口风吹雪的影响,取得了较好的效果。
If the snowy tunnel tunnel near the improper handling measures, on the one hand, wind and snow will lead to snow tunnel blockage, disruption of traffic; the other hand, the wind and snow will block and blur line of sight, the snow melted road icy, easily An accident happened. Taking the example of the design of the snowbreaks in the tunnel entrance of the G045 line from the Sailimu Lake to the Guozizigou Reconstruction Project, the numerical simulation of the tunnel entrances in the snowy area was carried out. The results provided a basis for the determination of the tunnel openings and solved the problems Tunnel hole blowing wind snow, and achieved good results.
