CRITICAL EVALUATION OF ROCK BEHAVIOR FOR IN- SITU STRESS DETERMINATION USING OVERCORING METHODS

Several significant developments in the interpretation and analysis of in situ stress measurements performed in weak rock using overcoring techniques are described. These developments include the critical appraisal of overcoring strain data, the determination of stress-strain transformation parameters for cross-anisotropic nonlinear rock, and the formulation of a numerical solution for cross- anisotropic rock. By suitable comparisons, it is shown that without these refinements meaningful results to the regional stress field could not have been obtained. The number of the covering abstract of the congress is TRIS no. 385148. (Author/TRRL)
