Comparison of In-Situ and Laboratory Test Results on Granite.

Abstract

Four NX-diameter holes were diamond-drilled in competent granite. Samples of the recovered core were used in laboratory tests. A borehole, plate-bearing device known as a Goodman jack was used to perform load-deformation tests on the rock in the core hole. The samples used in the laboratory tests were taken from depths in the hole at or within 5 ft of those at which the jacking tests were made. Bore-hole camera records, compressional and shear wave velocities, and densities were measured. Dynamic elastic constants were computed for the in-situ material, while comparative data (except camera records) were obtained in the laboratory.
