NettetThe empirical Hoek-Brown failure criterion is a well-known and commonly used failure criterion for both intact rocks and rock masses, especially in geological engineering. The intact criterion is calculated using experimental triaxial compression test results on intact samples while the rock mass criterion modifies the intact strength using quantified … Nettet1. jan. 2024 · In this independent review, the origin and evolution of the Hoek–Brown failure criterion and the associated strength degradation relations and rock mass …
