Rock mass quality and support recommendations for basalt at the candidate repository horizon, based on the Q-system

  • 1. Terra Tek, Inc., Salt Lake City, UT (USA)

Description

An analysis of the Q-system of rockmass characterization and tunnel support selection and its application to the candidate repository horizon is provided. The range of rockmass qualities, tunnel sizes and tunnel depths which constitute the Q-system database are reviewed and related to the quality of the candidate repository horizon, rock conditions equivalent to those in the candidate horizon are thoroughly documented. A detailed review of pertinent BWIP documents was undertaken to estimate general conditions and possible extreme conditions, and resulted in determining an extreme range of Q from 0.05 to 10 and a design range of 0.4 to 4. Detailed rock reinforcement recommendations, incorporating appropriate reinforcement for typical and extreme colonnade and entablature, were derived for roofs, walls and intersections in all planned tunnels. 35 refs., 31 figs., 19 tabs
