Mechanical Response and Instability of Granite with Parallel Non-Persistent Joints Under Rapid True-Triaxial Unloading: A PFC3D Numerical Study

Rapid excavation in deep rock masses imposes a non-proportional stress path that can destabilize jointed rock. A three-dimensional Particle Flow Code (PFC3D) true-triaxial model of granite containing two parallel non-persistent joints was used to examine the effects of joint leng...
