摘要

结合所略四级水电站引水隧洞工程地质条件,分析开挖施工过程中发生大塌方的原因,根据工程地质特点,在隧洞大塌方处采用超前管棚支护+槽钢支护+钢筋混凝土衬砌的方案进行处理。施工过程中,严格控制施工质量,顺利通过了塌方段,完成了隧洞开挖任务,目前隧洞运行良好。
        Combined with the engineering geological conditions of diversion tunnel of Suolue Cascade IV Hydropower Project,the author analyzed the causes for the massive landslides occurred during tunnel excavation. Treatment scheme was adopted according to the engineering geological characteristics,incorporating pipe shed advanced support with U-steel support and reinforced concrete lining. The following construction was conducted under strict quality control,which ensured smooth advancing through the collapsed section and completion of tunnel excavation. The tunnel is operating well now.
