| Abstract: | Combined with the engineering geological conditions of diversion tunnel of Suolue Cascade IV Hydropow-er 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 sup-port 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 excava-tion. The tunnel is operating well now. |
