... on an estimated average density of 2700 kg/cu.m. The average horizontal stress was considered to be extremely high based on measurements made elsewhere in the region. Herget's relationship (Figure 1) results in a horizontal to vertical stress ratio of 2.6 at a depth of 1200 meters, (σv = 32 MPa; σ...

... artificial rocks to document the failure process and to assess the influence of stress magnitude and far field stress ratios on the borehole breakout process. The major horizontal boundary stress, <JH, was varied between 14.5 and 19.4 MFa, the horizontal stress ratio, N (ratio of minor to major horizontal...

... peculiarity that the deviatoric stress at peak is not always in agreement with the value at max- imum effective stress ratio, that expresses somewhat the strain softening behaviour even in the region of normally consolida- tion. The stress path at closely consol- idation yield stress(30kgf/cm2 ) exhibits the...
