Abstract:

Both Ground Penetrating Radar (GPR) surveys and Hydro-Geochemical Water Testing (HGWT) have been performed at the Cumberland Gap Tunnel to determine why the reinforced concrete pavement has settled in various areas throughout both tunnels. To date, approximately 7,300 total square feet of pavement surface has voids beneath in that range from 0.05 to 40 inches in depth. Both GPR and HGWT results indicate that approximately 0.75 to 1.5 cubic yards of limestone sub-base material leaves the tunnel in solution form on monthly basis. Furthermore, HGWT results indicate that the ground water beneath the tunnels is calcium deficient. Thus allowing the water to dissolve the limestone sub-base. Approximately 500,000 to 1 million gallons of water flows through the tunnel's ground water collection system on a daily basis.
