... ABSTRACT: The Hoek-Brown (HB) strength criterion is increasingly used to investigate the stability of slopes. However, it is still partly unclear how this should be implemented for slopes in a correct way. There are two ways to use the HB strength criterion. On the one hand, the HB parameters...

With these numerical simulations, the construction process of the tunnel is studied to analyze its influence on the existing slope stability, along with the corresponding...

... ABSTRACT: Conventional triaxial compression tests were conducted on dry cylindrical samples of three silicate and three carbonate rocks with porosities in the range 0.3%-24.0%, and confining pressures 0-70 MPa, in order to determine the constant m i of the Hoek-Brown criterion for intact rock...

At deep tunnels, as one moves from the excavation surface into the rock, the fracture mechanism changes from extensional to shear cracking. The representative Kannur limestone is observed to exhibit exquisite extensile fractures as columnar...
