[CS17-06] A case study of change in water leakage and precipitation of tunnel lining using abandoned road tunnel
Keywords:Abandoned road tunnel, water leakage, maintenance, accumulated rainfall, effective rainfall
Since the leakage of the tunnel may change depending on the amount of groundwater in the ground around the tunnel, the location and the amount of leakage may differ after the inspection of the tunnel and may not be accurately understood. In this paper, the surface of the tunnel lining was photographed at different times when the groundwater flow was assumed to be different, and the leaked area was calculated.
