INTEGRATED APPROACH TO GEOTECHNICAL ASSESSMENT OF ROCK TUNNEL STABILITY AND PERFORMANCE . TUNNEL CONSTRUCTION 90. PAPERS PRESENTED AT THE TUNNEL CONSTRUCTION 90 CONFERENCE, ORGANIZED BY THE INSTITUTION OF MINING AND METALLURGY, LONDON, 3-4 APRIL, 1990

This paper reviews excavation design procedures and discusses an integrated approach to geotechnical data acquisition for tunnelling, highlighting the necessity for efficient data exchange, utilisation, and representation. The potential application of novel technologies to site investigation is discussed, within the framework of an integrated approach. For the covering abstract of the conference see IRRD 828810.
