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 ... WebThe Hoek-Brown strength criterion was introduced to simulate the failure mechanism of jointed rock and triaxial compression tests of fractured rocks (Hoek and Brown 1980a, b …

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.
