| Abstract: | The project profile,engineering geology and hydrogeologic conditions of Dayaoshan tunnel are introduced.A water gushing spot with high water pressure was found in the tunnel sandstone areas.The pressure was 3-4 MPa at the outgushing point.The flow amounted 430 m3/h,the spraying distance reached 47m caused by the hydraulic head.Combined techniques of diversion and drainage measures,construction of water-stopping wall,intermittent grouting and full-face curtain grouting were adopted to successfully tackle the... |
