Hoek–brown failure criterion—2002 edition
NettetRSData implements the most recent update (the 2002 edition) of the Generalized Hoek-Brown criterion. This edition resolves some formerly troublesome issues including: The applicability of the criterion to very weak rock masses, and The calculation of equivalent Mohr-Coulomb parameters from the Hoek-Brown failure envelope The Generalized … NettetHoek-Brown failure criterion – 2002 Edition.

NettetHoek and Brown [1, 2] introduced their failure criterion in an attempt to provide input data for the analyses required for the design of underground excavations in hard rock. The criterion was derived from the results of research into the brittle failure of intact rock by Hoek [3] and on model studies of jointed rock mass behaviour by Brown [4 ... NettetProc.

The most well-known version in 2002 (Hoek et al. 2002) incorporated field tests of highly fractured rocks into the model. The following mathematical form of HB yield criterion can be expressed as:

NettetThe original Hoek-Brown failure criterion was introduced with this equation (Figure 2) where σ1 and σ3 are the major and minor principle stresses at failure, Co is the uniaxially compressive strength of intact rock, and m and s are empirical constants depending on the type of rock.

NettetMORE The Hoeke Brown criterion was introduced in 1980 to provide input for the design of underground excavations in rock.
