4. 3. Analysis of shear strength of rock joints with PFC2D

   University essay from KTH/Jord- och bergmekanik

   Author : Elisa Lazzari; [2013]
   Keywords : PFC2D; rock joints; peak shear strength; smooth joint contact model; numerical shear test.;

   Abstract : Joints are the main features encountered in rock and sliding of rock blocks on joints is classified as the principal source of instability in underground excavations. In this regard, joints’ peak shear strength is the controlling parameter. However, given the difficulty in estimating it, shear tests are often performed. READ MORE
