Abstract: Drilling for field testing and laboratory testing was carried out for the U. S. Army Engineer District, Chicago, as part of a stabilization program at the Brandon Road Dam on the Illinois Waterway. A previous stability investigation concluded that all sections of the dam failed to meet current overturning criteria. It was recommended that the dam be stabilized by installation of grouted, prestressed tendons. This report presents physical property data of concrete and foundation rock for use in a stability analysis and the design of an anchorage system involving grouted steel tendons. A down hole teleview was used to obtain orientation of natural discontinuities in the foundation rock. Pressure transducer measurements were taken in the field in order to monitor uplift pressures at the base of the dam. Laboratory testing included the determination of characterization properties (compressive strength, unit weight, tensile strength, compressional wave velocities) and engineering design properties (elastic moduli, triaxial strength including multistage loading, direct shear of intact and discontinuous rock samples, and consolidated-undrained (R) and drained (S) triaxial strength of overburden samples).
