摘要
以兰渝铁路柳家河隧道工程为例,从超前支护、爆破设计、初期支护、二次衬砌等方面对软弱千枚岩段的施工方案进行了介绍,并对隧道净空收敛沉降进行了监控量测,结果证明支护参数合理,全断面开挖可行。
Taking the Liujia river tunnel project of Lan-Yu railway as an example, this paper introduced the construction scheme of soft phyllite from advanced support, blasting design, primary support, secondary lining and other aspects, and made monitoring and measurement to tunnel convergence settlement, the results showed that the support parameters reasonable, full section excavation feasible.
