Abstract

The Pre-Cambrian rocks comprised of granites and gneisses are generally competent. The rocks are, however, jointed and intruded by dykes of younger rocks resulting in weak interfaces which may cause localized ground control problems. A brief description of important rock types and their geological and mechanical characteristics is presented. The design criteria and procedures of rock excavation and tunnel support and reinforcement are discussed. The need for using feed-back from construction and operational experience as well as local research effort in the updating of design criteria is emphasized.
