Abstract

Subway tunnel condition assessment presents significant challenges for engineers, and is becoming increasingly important as the systems continue to age. Technologies are needed that can rapidly and accurately assess the condition of subway tunnels, and identify distress such as delamination, moisture-related damage, without interfering with the normal operation of the system. Towards this goal, different nondestructive evaluation methods including SASW, Impact Echo, GPR, and Impulse Response were evaluated to determine their advantages and limitations for tunnel evaluation. Since tunnels are in constant heavy use in an aggressive environment, it is necessary to distinguish between methods that can be used for high speed screening, and those that require interruption of subway traffic. It is also necessary to develop automated procedures to process the vast amounts of data generated during extensive NDE testing.
