TWO METHODS FOR DETERMINING ULTIMATE BEARING CAPACITY OF ISOTROPIC ROCK FOUNDATION UNDER SHEAR FAILURE MODEL

Shear failure is a most common failure in rock foundation, which often takes place in intact , jointed and weak rock foundations. On the basis of Hoek-Brown strength criterion and limit equilibrium method, the authors introduce two methods for determining ultimate bearing capacity. Finally, an engineering example from chongqing is offered in order to prove the methods to be reliable.
