STUDY ON MOUNTAIN TUNNELS WATER-REDUCING MEASURES AND TUNNEL BEHAVIORS BY POST GROUTING

As a measure to preserve groundwater environment during the construction of mountain tunnels, usually waterproof materials are injected around the tunnel to control the leakage of spring water. However, there have been only a few examples on the use of post grouting for the injection of waterproof materials after tunnel excavation. In this research, the authors present a design and construction method for the injection of waterproof materials by post-grouting using a dam consolidation grout method and examine its effects based on construction data. In addition, the authors analyze the tunnel behaviors at the time of groundwater recovery at a level exceeding 150 m following the injection of waterproof materials, and discuss the applicability of water-reducing measures under a high groundwater level condition.
