| 摘 要： | 三道湾水电站引水发电洞围岩主层为变质砂岩夹千枚状板岩,其岩质较差,地质构造复杂,大部分为Ⅳ类围岩。对此类围岩采用“新奥法”施工方法,即一次支护,二次永久衬砌施工和灌浆处理,并在一次支护完成后进行了收敛量测。且获得了成功,保证施工顺利完成。

| Abstract: | The adjacent rock of power tunnels for Sandaowan hydropower station is mainly metamorphic sandstone with phyllite slate,and its rock quality is poor with complicated geological structure.It belongs to Grade IV adjacent rock.New Austrian tunneling method was adopted for the primary support,secondary permanent lining and grouting treatment,and the convergence survey was performed after the primary support.It has obtained a successful results to guarantee smooth completion of the project. |
