| 摘 要： | 易隆隧道是曲嵩高速公路上行线一座单线三车道隧道,隧道穿越围岩滑塌体,埋深为30m～94m,属浅埋隧道,洞内岩体破碎松散,通过采用大管棚法施工,易隆隧道已经顺利通过洞内的滑塌体,既保证了既有高速公路通车,也保证了洞内不发生塌方等安全事故。实践证明：大管棚法是一种安全、快速、高效地通过洞内滑塌体的施工方法。

| Abstract: | Yilong tunnel is a single-line three way tunnel on the uplink of Qujing-Songming expressway. The tunnel traverses the gliding mass of wall rock, and the depth of burial is 30m-40m. It belongs to shallow tunnels. The rock in the cavity is broken and incompact. By big pipe-roof construction, Yilong tunnel has traversed the gliding mass in cavity successfully, which ensures that the expressway will be open to traffic and the accidents such as landslide will not occurs in the cavity. The practice proves that big pipe-roof method is a safe, fast, and highly efficient construction method for traversing the gliding mass in cavity. |
