Abstract

Abstract: According to the principle of fitting non-linear strength criterion with linear M-C criterion in σ₁-σ₃ plane, we derived the equivalent M-C strength parameters of the Sheorey strength criterion which is based on the RMR system by use of the least square method. We also present the general formulas of the equivalent M-C strength parameters to be used in the evaluation of strength and stability of rock mass. A calculation example is given to compare the M-C strength parameters between Sheorey criterion and Hoek-Brown criterion. Results reveal that the strength parameters of both criteria are well consistent.

Key words: rock mechanics, Sheorey strength criterion, Mohr-Coulomb criterion, least square method, equivalent strength parameters
