WebIn situ stresses affect rock mass properties in a number of ways. Some of these effects, shown earlier in Figure 27.5, are stated in the following list (Hudson, 1992): • Stronger rock can sustain higher in situ stress. • Stress concentration decreases with displacements. • In situ stresses normal to discontinuities with large aperture ...
