摘要
Paper presents general hypothesis of the relationship between the strength of rocks and the third invariant of the stress tensor deviator at failure. It has been assumed that the normal and tangential stresses acting on the strictly determined planes defined by the directional cosines depending on the three invariants of the stress state should be taken into account in the calculation of the rock strength. The hypothesis is the extension of the former Burzynski's work. Geometrical interpretation of the hypothesis has been given and its verification for Sandstone and Dunham Dolomite, on the basis of experimental data known from the relevant literature, has been presented.
