Ultimate bearing capacity of rock masses based on the modified Hoek–Brown criterion

Displacement-based seismic design of a shallow strip footing positioned near the edge of a rock slope

“…[8][9][10][11], in addition to being used in the pseudo-static procedure, can also be employed to determine the horizontal critical coefficient for any given load acting on the footing. This assumes that it acts only the horizontal component of the acceleration.…”

“…The modified Hoek-Brown criterion has been used by several authors to calculate the bearing capacity of a strip footing resting on a horizontal rock surface in static conditions [7][8][9][10][11][12] and the stability of rock slopes both under static [13][14][15] and seismic conditions [16][17][18].…”

Numerical investigation on the bearing capacity of two interfering strip footings resting on a rock mass

“…Important studies were carried out to assess ultimate bearing capacity of rough strip footings rest upon rock masses [12][13][14][15][16][17]. Nevertheless, the authors are not aware of any published paper about the bearing capacity of two interfering foundations resting on a modified Hoek-Brown material.…”

The effect of the intermediate principal stress on the ultimate bearing capacity of a foundation on rock masses

“…The methods for the bearing capacity can be mainly classified into the following four categories: (a) the slip line method [1][2][3][4][5][6], (b) the limit equilibrium method [7][8][9], (c) the limit analysis method [10][11][12][13], and (d) finite element or finite difference numerical techniques [14,15]. Among these methods, the slip line method has proved its usefulness in estimating the ultimate bearing capacity.…”

“…Among these methods, the slip line method has proved its usefulness in estimating the ultimate bearing capacity. For example, Sokolovskii developed the slip-line equations for a Coulomb failure criterion [3]; Salençon derived the slip-line equations for an arbitrary curved strength envelope [4]; Serrano & Olalla defined the slip-line equations for Hoek-Brown criterion [5]; and Serrano et al derived the slip-line equations for the modified Hoek-Brown criterion [6]. These mentioned efforts were focused on the linear Mohr-Coulomb (MC) failure criterion, in which effects of intermediate principal stress and discontinuities on rock strength are not taken into account.…”
