One of the most important aspects of designing a structure on or in a rock mass is based on the strength response of a jointed
rock mass. Understanding this important aspect, the present study was undertaken to understand the strength response of a
jointed rock mass with the help of a finite difference package FLAC
3D. In the present work, an attempt has been made to understand the effect of discontinuity angle on the failure mode and strength
of the rock mass. For this purpose, stress and displacement in the model were studied and various stress–strain histories
were recorded at constant strain loading rate. Rock discontinuity plays a critical and vital role to understand physico-mechanical
characteristics of a rock mass. It has wider application in the rock excavation engineering, e.g., caverns, tunnels, slope
stability, dams, etc. Simulated rock results are compared with the analytically calculated results of the jointed rock mass
and found in good agreement.
