RATIONAL DESIGN OF TUNNEL SUPPORTS: AN INTERACTIVE GRAPHICS BASED ANALYSIS OF THE SUPPORT REQUIREMENTS EXCAVATIONS IN JOINTED ROCK MASSES

In the configurations used in this report, the Distinct Element method is coupled to a graphics terminal so that movements of the blocks are visually available. A survey of the methods used to analyze the behavior of jointed media is presented. Numerical verification of the Distinct Element method is provided. In particular, several comparisons to limit equilibrium solutions are presented. The discussion covers two topics: excavations that are stable without external support, and excavations that require external support.
