| Abstract: | The gushing water in the Huama Tunnel shows the main characteristics of being large in volume, high in pressure, strong in inter-connectivity and steady in waterhead, etc. The characteristics and properties of the gushing water are obtained by means of detailed geological exploration, advanced forecast of geological conditions, and performing advanced drilling to explore hydrogeological conditions, upon the basis of which a composite treating scheme of avoidance by circuitous heading in combination with the discharge tunnel is proposed. With the composite treating scheme adopted and the drainage for the tunnel properly dealt with, the excavation is safely performed through the section with gushing water. |
