Vahab Sarfarazi, Hadi Haeri and Alireza Bagher Shemirani

Abstract

Rock bridges in rock masses would increase the bearing capacity of Non-persistent discontinuities. In this paper the effect of ratio of rock bridge surface to joint surface, rock bridge shape and normal load on failure behaviour of intermittent rock joint were investigated. A total of 42 various models with dimensions of 15 cm

Key Words

rock bridges; joint; normal loads; shear and tensile failure mode
