Underground research laboratory room 209 instrument array. Pre-excavation information for modellers
An in situ excavation response test was conducted at the Canadian Underground Research Laboratory (URL) in conjunction with excavation of a tunnel (Room 209) through a near-vertical water-bearing fracture oriented almost perpendicular to the tunnel axis. Encountering a fracture with such desirable characteristics provided a unique opportunity during construction of the URL to try out instrumentation and analytical methods for use in the Excavation Response Experiment (ERE), one of the major URL experiments. This is the first of four reports that cover the excavation response test. This report contains the information provided to the numerical modelling groups before the start of excavation. It includes survey information of the excavations within 30 m of the instrument array; the layout of the instrument array; details of the geology, rock properties, joint characteristics, in situ stresses, and in situ rock temperature distribution; the results of hydrogeological testing and monitoring; the planned excavation sequence; and the format for the modellers to present their results to facilitate easy comparison with the measured responses. Includes 13 excavation charts in back pocket. (Atomindex citation 22:068694)
