NONDESTRUCTIVE EVALUATION OF SELECTED DRILLED SHAFTS AT THE CENTRAL ARTERY/TUNNEL PROJECT
Impulse response tests were conducted on 3- and 8-ft (0.9- and 2.4-m) diameter drilled shafts used for support of bridge piers at the Central Artery/Tunnel Project in Boston. Shaft length-to-diameter ratios varied from 12 to 34. This paper describes the testing procedures and data reduction techniques, summarizes the results of the nondestructive testing, and evaluates the capabilities of the method. Results of the tests indicated the propagation velocities based on the impulse response tests were comparable to that of "good" quality concrete and the mobilities were within the range of those expected for shafts constructed with the design diameters of each shaft. However, the portions of the shaft embedded in rock were not sensed significantly by the induced stress waves.
