ABSTRACT
The accurate analysis of rock with joints is urgently needed to improve the predictions of rock behavior and to design the support of underground caverns reasonably. Horii and Yoshida proposed a Micromechanics Based Continuum (MBC) model that enables to take the opening and shear slip of joints into account by replacing the rock mass containing joints with an equivalent continuum. This study applied the MBC model to a cavern excavation analysis and examined its applicability to the design of cavern support.
