ABOUT ROCK STRENGTH CERTIFICATE

Year 2020, Volume 4, Issue 5, 18 - 31, 28.12.2020

Abstract

The stress state of rocks in the massif is modeled by testing standard cylindrical specimens on equipment according to the Karman’s scheme, when some the ratio between the axial compressive stress and the principal stresses from uniform lateral pressure is given. In this case their ratio at the time of destruction indicates the strength of rocks. These stresses can take many values, and it is impossible to carry out the whole complex of experiments with different ratios of these components. Therefore, various methods of calculation are being developed, which can be used to estimate the degree of danger of the stress state by the postulated dependencies between the main stresses, i.e. to predict the strength properties of materials at the moment of destruction.

The envelope of limit stress circles on the Mohr’s diagram in the coordinates “normal stress - shear stress” is considered as the rock strength certificate. To construct the envelope was used the relationship between the maximum and minimum principal stresses, presented in the form of two different strength criteria. One of them is the well-known criterion of Hoek-Brown, the other is proposed recently by T.B. Duyshenaliev and K. T. Koichumanov. The applicability of these criteria was checked on A.N. Stavrogin's and K. Mogi's experimental data, which were received by testing cylindrical specimens of various rocks under triaxial compression, as well as in the case of uniaxial tension.
