Underground research laboratory room 209 instrument array. Numerical modellers' predictions of the rock mass response to excavation
An in situ excavation response test was conducted at the 240 Level of the Underground Research Laboratory (URL). The test was carried out in conjunction with the drill and blast excavation of a near-circular tunnel, about 3.5 m in diameter. The tunnel was excavated through a near-vertical water-bearing fracture oriented almost perpendicular to the tunnel axis. Three modelling groups made predictions of the response of the rock mass and hydraulic behaviour of the water-bearing fracture to excavation. Two of the groups used the three-dimensional Finite-Element Method and one group used the Discontinuous Deformation Analysis Method. Both methods predicted displacements and stress changes that agreed reasonably well with the measured response, but none of the methods predicted the hydraulic response of the fracture.
