Abstract:

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.
