| Abstract: | Based on the anisotropic elastic theory of the rock body, the X-ray diffraction method is adopted to measure the core samplings extracted from 12 selected large aperture boreholes in the area along the Red River fault zone. The 3-D macro- and micro- residual stresses in rocks and their elastic strain energy density distributions with depth are measured. The regularity of such a distribution with depth is analysed. |
