摘要
铁峰山2号隧道是重庆万(州)-开(县)高速公路控制性工程之一,隧道左右线长度均超过6 000m,隧道穿越的地层复杂,存在突水、煤层瓦斯、煤巷采空区、石膏岩地层、软岩变形、岩爆等不良地质现象,工程地质条件极为复杂,施工难度大,施工防护要求高。本文就此隧道施工中顺利通过以上复杂路段的工程措施进行了研究。
Tiefeng rock tunnel is a control project in Wanzhou-Kaixian expressway. The length of the tunnel exceeds 6 000m. The geological conditions of the tunnel are very complex, including groundwater ingression, firedamp, gypsum strata, soft rock deformation, rock outburst etc. The construction is difficult. Some construction methods are studied for Tiefeng rock tunnel to pass the complex zone mentioned above. Some valuable results are given. The conclusions can be referred by similar extra long rock tunnel projects.
