遮雪棚在河北省张承高速公路桦皮岭隧道中的应用

Application of Snowshed in Zhang-Cheng Highway Huapiling Tunnel in Hebei Province

降雪量大且地势低洼处的隧道洞口容易积雪,为防止运营期间积雪影响隧道运营安全,需在隧道洞口设置遮雪棚。结合桦皮岭隧道洞口遮雪棚的工程实例,介绍了遮雪棚的设计与施工情况。

Snows stay easily at the entrances of low - lying tunnels located at mountains with heavy snowfall. To prevent tunnel operation from heavy snows, snowshed needs to be built at tunnel entrances. Combined with the project case of snowshed at the entrance of Huapiling tunnel, the design of the snowshed and construction process has been introduced.
