STRESS-STRAIN RELATIONS APPLICABLE TO OVERCORING TECHNIQUES IN TRANSVERSELY ISOTROPIC ROCKS

Stress-strain equations for use with stress measurement overcoring techniques are given for transversely isotropic materials. The equations are given for the CSIR triaxial strain cell and the CSIRO HI (hollow inclusion) cell for two borehole orientations relative to the isotropic plane. Determination of the elastic material properties required is discussed and an example of measured results evaluated in terms of the theory is given. (Author/TRRL)
