Abstract:
Taking the construction of the waterrich and fractured portal section of smallnetspaced Hengshan tunnel on YongWu highway as example, the author systematically presents the comprehensive construction technology for smallnetspaced tunnels located in waterrich and fractured regions, including the optimization of the excavation plan, the reinforcement technology (with the emphasis being placed on the consolidation of the rock pillars and the strengthening of the reinforcement system) and the rich water treatment (i.e., wellpoint dewatering). The presented construction technology demonstrates that the construction plan is safe and economic.
