Nondestructive testing of bridge decks and tunnel linings using impulse-response
Because of the limited time available for on-site testing of bridges or tunnels, mainly due to the high costs for regulation of the traffic, the use of nondestructive testing has set new standards for how large an area of a structure and how much valuable information that can be acquired within just 1 day of testing. However, it is vital that the staff is well trained in the underlying theory as well as the operation of the equipment and has knowledge about the structures being tested, otherwise, lots of worthless data is collected. Verification of the data interpretation at each site is vital to ensure that the data have been evaluated correctly. This paper evaluates the impulse-response method in some typical testing cases, where the method has been used to locate delaminations in two bridge decks and in the ceiling of a submerged tunnel. The data has been presented in various contour plots and mobility plots of impulse-response parameters. For each case, the interpretation of the data has been verified by drilling cores.
