A Theoretical Method for Evaluating Stability of Openings in Rock

Abstract

The purposes of this study are to evaluate the reliability of the available finite element techniques for the solution of plane problems to predict the stresses, strains, and deformations in a rock mass surrounding an excavation. The approach to this study is divided into two phases: developing a general analytical procedure (i.e., a finite element computer program with wide capabilities) for determining the mechanical state in a rock mass, and analysis of case histories to compare predicted and observed values.
