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: (1) 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 (2) analysis of case histories to compare predicted and observed values. This report discusses essential features of finite element techniques for modelling rock behavior and describes the development and verification of a single general computer program which is capable of modelling mints, faults, bedding planes or other geologic discontinuities, no tension' properties and elasto-plastic behavior of rock masses.
