Hoek–Brown failure criterion - Wikipedia

Scientific Research An Academic Publisher. Affiliation s. Analytical, observational, and empirical are the main design approach for excavations in rock. Rock mass classifications as practiced in civil and mining engineering form an integral part of the empirical design methods, which is the most predominant design approach [1]. The main objectives of the rock mass classifications are to identify the most significant parameters influencing the behavior of a rock mass, divide area into rock mass classes of varying quality and provide quantitative data for engineering design purpose. Rock mass classifications have played an important role in estimating the strength and deformability of rock masses and in assessing the stability of rock slopes. They were also shown to have special uses for serving as an index to rock rippability, dredgeability, excavatability, cuttability, and cavability.

The Art of Tunnelling in Rock

The Hoek—Brown failure criterion is an empirical stress surface that is used in rock mechanics to predict the failure of rock. Brown in for the design of underground excavations.

Hoek–Brown failure criterion

Cavity Expansion Methods in Geomechanics pp Cite as. Underground excavations and tunnelling involve the removal of soil or rock masses from their initial locations. This action reduces and, in some cases i. Therefore, it may be reasonable to assume that the action of tunnelling and underground excavation can be modelled by the unloading of a cavity from the in-situ stress state.
