| Abstract: | The water-gushing in Huama Tunnel is what called high-pressure fracture-karst water which is characterized by large quantity, high pressure, continuous supply, smooth flow, and stable source. By detailed geological survey, hydro-geological condition analysis, and precise geological prediction, the feather and quality of the water-gushing is known and treatment measures with water detouring and draw-off culvert are used to move through the water gushing section. |

| Keywords: | Key words tunnel water-gushing fracture-karst water geological prediction advanced horizontal drilling detouring draw-off culvert |
