摘要
新建铜九铁路Z4标段刘家湾隧道施工区段为带有微膨胀性的红粘土,隧道顶土体厚度2~10m,采用明挖法施工,重点介绍了土石方开挖、边坡支护、主体施工等关键技术,对类似工程有借鉴意义。
The Liujiawan Tunnel in Z4 part of Newly built Tongjiu Railway(from Tongling in Anhui Province to Jiujiang in Jiangxi Province) is located in red clunch area with micro-expanding characteristics. The earth height on the top of tunnel is 2-10 m. The tunnel is constructed by use of the open excavation method. The excavation course, the slope timbering, the main construction and other key technique are especially introduced. The results can provided reference values for similar engineering.
