摘要
结合某软岩隧洞工程概况,确定了隧洞的施工方案,并就隧洞开挖、支护、混凝土衬砌的施工方法作了介绍,得出断面分区开挖的施工方法在软弱围岩中极为实用,可提高工效,加快施工进度。
Combined with engineering situations of one soft rock tunnd works the construction scheme of this tunnel is determined. Detailed introduction is made on the construction methods of tunneling, supporting and concrete lining. One conclusion is obtained that the sectional tunneling construction method is practical for soft wall rocks, which greatly increase the work efficiency and shorten time limit.
