Determining Unknown Bridge Foundation Depth by Resistivity Imaging Method

Determining unknown foundation length and type of bridge foundation is becoming an important concern for state departments of transportation (DOTs) to ensure the safety of the bridge. Based on specific site conditions and type of foundation to be tested, there are several methods available to determine unknown foundation depth. Resistivity Imaging (RI) is a nondestructive method to investigate the subsurface condition. The objective of the current paper is to investigate the applicability of RI for determining unknown foundation depths. RI tests were conducted on two bridges located in North Texas. The first investigated bridge was supported by driven steel H-pile and the other bridge had drilled shaft as foundation. The investigated bridge foundation depths were compared with the actual foundation depths. The determined foundation depth utilizing RI was found very close to actual foundation depth for the first bridge supported by steel H-pile. However, for the second site, the determined depth of foundation did not match with actual depth of foundation.
