摘要
大循高速公路卧龙沟隧道地跨青海、甘肃两省,位于黄土高原向青藏高原过渡区间带,隧道总转角近220°,为西北高原高海拔地区首条小半径螺旋形隧道。本文通过卧龙沟隧道来探讨"一种用于超前小导管注浆的快速注浆套筒"在超前支护中应用的技术可行性及经济适用性。
The Wolong highway tunnel across Qinghai and Gansu Province, located in transition zone between the Loess Plateau and Tibetan Plateau. The tunnel is the first small radius spiral tunnel in the northwest region of high altitude plateau with the tunnel total angle near 220 degrees. In this paper, the technical feasibility and eco- nomic applicability of quick grouting sleeve in advanced support is discussed with Wolong tunnel.
