SPECIALIST TUNNELLING PROCESSES . TUNNEL CONSTRUCTION 90. PAPERS PRESENTED AT THE TUNNEL CONSTRUCTION 90 CONFERENCE, ORGANIZED BY THE INSTITUTION OF MINING AND METALLURGY, LONDON, 3-4 APRIL, 1990

Many specialist techniques are currently available to assist the tunneller in proceeding safely and economically, even in adverse ground. These are reviewed in the paper which is specifically written for driven tunnels, although many of the techniques can be used successfully in cut and cover operations. Techniques reviewed include: (a) site investigation, by drilling inclined or horizontal holes as well as vertical boreholes, in order to locate faults and to determine the weathered profile of the rock; (b) ground dewatering; (c) ground support; and (d) ground treatment, including cyrogenic processes, pressed air working is also discussed briefly, as is pipe piling and the New Australian Tunnelling method. A comparison of the costs and safety aspects of various specialist techniques (ground treatment, such as grouting, freezing, compressed air, tunnel support, dewatering and the use of sophisticated shields) is also provided. Contract aspects are discussed briefly. For the covering abstract of the conference see IRRD 828810.
