Abstract

A three dimensional small displacement rigid block formulation is developed to perform static and dynamic analysis of rock masses. Blocks are formed from the interaection of multiple sets of joint planes defined by their strike, dip and spacing. Interaction between blocks is modeled so as to occur along their common contact planes and is also limited to small relative displacement. Implicit and explicit formulations are developed for static analysis whereas explicit formulation is developed for dynamic analysis. Elasto- plastic behavior is assumed in shear along the joints and plastic sliding involves local dilation. Fürthermore, this model features the possibilities of excavation, stabilization with rock bolts and its boundaries can be non-reflective.
