The Hoek–Brown Failure Criterion - Springer
Web26 Jun 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.

Through and Overflow Rockfill Dams SpringerLink
WebRIS. All large triaxial shear tests on rockfill specimens to date indicate that the shearing strength of rockfill, as expressed by its friction angle, varies markedly as a function of normal pressure, being high at low pressures and substantially smaller as normal pressures increase. At normal pressures less than about 10 psi, friction angles ... Web16 Nov 2024 · The failure criterion was then published by Dr. Hoek and Dr. Brown in 1980 and first used for underground excavation of hard rock with confined conditions. The … WebThe origins of through and overflow rockfill dams can be traced, in Australia at least, to the Cascade Dam (Fig. 1), built to supply sluicing water to the Briseis alluvial tin mine at Derby in north-east Tasmania (Anon, 1989). It was to enter the annals of history as the only large dam in Australia to fail causing loss of life. oxford cycle works
