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. Figure 2: Original Hoek-Brown Failure Criterion Equation Nettet10. nov. 2024 · The Hoek–Brown failure criterion is an empirical stress surface that is used in rock mechanics to predict the failure of rock. [1] [2] The original version of the Hoek–Brown criterion was developed by Evert Hoek and E. T. Brown in 1980 for the design of underground excavations. [3] In 1988, the criterion was extended for …
NettetThis study communicates a novel seismic stability assessment of rock slopes based on the concept of the limiting slope face (LSF) combined with the method of stress characteristics (MSC) and the modified pseudo-dynamic (MPD) approach. The slope geometry with a target factor of safety (FS) of 1.0 is derived, precluding the need for any preordained … Nettet18. sep. 2024 · Hoek-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 ... Nettet1. jan. 2016 · The Hoek-Brown criterion is an empirical, rock mass failure prediction criterion based on the relationship between principal stresses. The Hoek-Brown criterion was developed in the late 1970s and first published in 1980 (Hoek and Brown 1980a, b) to provide input for the design of underground excavations (Eq.
