DETERMINATION OF UNKNOWN BRIDGE FOUNDATION DEPTHS WITH NDE METHODS

This paper discusses the results of National Cooperative Highway Research Program (NCHRP) project 21-5 and 21-5(2) sponsored research on nondestructive evaluation (NDE) methods for determination of unknown bridge foundation depths. Surface and borehole NDE methods are reviewed along with a discussion of the limitations and accuracy of the NDE techniques. The NDE methods found to be applicable to unknown foundation depth determination were the borehole methods of Parallel Seismic, Induction Field, and Ground Penetrating Radar, and the surface methods of Ultraseismic, Sonic Echo/Impulse Response, Spectral Analysis of Surface Waves, and Bending Waves methods. The research further found that the Parallel Seismic and Ultraseismic were the most accurate and broadly applicable borehole and surface methods and these are discussed in detail herein.
