WebA.2 Hoek-Brown criterion. The Hoek–Brown empirical rock failure criterion ( Hoek and Brown, 1980, 1997) was developed in the early 1980s for prediction of ultimate strength of intact rock and rock masses. This empirical criterion uses the uniaxial compressive strength of the intact rock and introduces two dimensionless strength parameters, m ... WebHoek brown 1.

WebJun 26, 2011 · ABSTRACT. The intact rock constant, mi, is one of the three basic input parameters required for the widely used Hoek-Brown failure criterion. In the absence of laboratory testing, guideline charts with mi values based on rock type have been provided by Hoek & Brown and others. Our analysis of existing databases on rock material …
WebAs an empirical criterion, the Hoek–Brown criterion has been updated several times in response to experience gained with its use and to address certain practical limi-tations (Hoek and Brown 1988; Hoek et al. 1992, 1995, 2002). These primarily involve adjustments to improve the estimate of rock mass strength. One key update was the
WebIt is important to note that for intact rock, the parameters of the Generalized Hoek-Brown criterion are as follows: s = 1. GSI = 100. a = 0.5. therefore the Generalized Hoek-Brown equation reduces to the following: This is the equation which is used for the curve fitting of triaxial lab data (intact rock) to the Hoek-Brown criterion. gwave 2008 1st experienceWebLinearization of Hoek-Brown criteria in general stability analysis of rock slopes.

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. In 1988, the criterion was extended for applicability to slope stability and surface excavation problems.
