Abstract

The article discusses natural stress field variation with depth. Rocks are assumed to be elastic. Increase in the stress level results in higher principal shear stresses but causes no failure. It is stated that failure is only possible at the increased lateral earth pressure coefficients, which induce hydrostatic stress redistribution at great depths. It is shown that Poisson’s ratio tends to 1/2 in isotropic rock mass.
