Development and Applications of Theoretical Methods for Evaluating Stability of Openings in Rock

Abstract

The purposes of this study are: (1) To incorporate into the finite element computer program for plane strain analyses, the capability to model and analyze: (a) structural support schemes used in the construction and design of tunnels, and (b) excavation techniques and construction and excavation sequences in underground construction. (2) To evaluate the analytical method developed in (1) by a study of case histories. The report discusses the available information on excavation techniques, construction and excavation sequences, the mechanisms of ground support and the current design techniques for support schemes.
