Imaging Voids Beneath Bridge Bent Using Electrical Resistivity Tomography
Five electrical resistivity tomography (ERT) profiles and borehole control were acquired beneath two bridges on the bank of the Gasconade River in order to determine extension of the underground water-filled openings in rock encountered during a drilling program, to locate other possible water-filled rock openings, and to map variations in rock quality in immediate proximity to the bridge foundations. The geophysical program was successful. Two east-northeast trending fracture zones were identified. Competent rock was differentiated from fractured rock. Extend of the water-filled rock opening was mapped based on the geophysical, borehole and grout data. A conceptual model of the development of the water-filled opening was proposed.
