HIGH PRESSURE CONSOLIDATION GROUTING FOR TUNNEL
SECTIONS WITH UNFAVORABLE GEOLOGY CONDITION |
|
|
|
|
Abstract The diversion tunnel of Tianshengqiao-2 hydropower station is characterized with large length， considerable embedded depth，high outer-water pressure，very complicated geologic and hydrogeologic conditions. During construction，the unfavorable tunnel sections with fault and fragment，karst caves and blind rivers are strengthened with either the high-pressure consolidation grouting or installing bolts in grouting holes. Consequently，very good results and construction experiences are gained.
