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.
