Rock Anisotropy and the Theory of Stress Measurements

Any undisturbed rock mass is subject to natural stresses inclu­ ding gravitational stresses due to the mass of the overburden and possibly tectonic stresses due to the straining of the earth''s crust and remanent stresses due to past tectonism. Knowledge of the in situ stress field must be integrated into any rock engineering design along with general rock mass characteristics such as de for­ mabi...
