Non-Destructive Evaluation of the Thickness of Linings and Pavements in Two Tunnels Using Ground Penetrating Radar.

摘要

The objectives of this project involved determination of the following parameters using a combination of non-destructive and traditional test techniques, with additional limited coring for validation purposes: 1. Thickness of the concrete lining in both tunnels at the crown and spring line areas. 2. Depth of the base of the tunnel linings below the pavement. 3. Depth to bedrock in the driving lanes of both tunnels. 4. Depth to bedrock in the approach roadways of both tunnels.
