------------------------------------------------------------------- Calibration data set from laboratory rock sample tests Record Control Number : 30550 Quality Validation Date : 2003-09-11 Update Date : 2003-09-25 Abstract : True tri-axial short-term strength tests have been performed on rock samples. The samples have been taken through a 4-stage stress history that allows the effects of stress and damage to be individually quantified. The samples are damaged in such a way to induce an aligned set of micro-cracks (transversely isotropic) . A stress probe technique has been utilised to allow static modulus values to be determined at different regions of the stress history. Additionally ultrasonic velocity measurements have been taken in each of the three principal directions of the sample. The data has been processed for: - Static modulus values. - P-, S1-, and S2- velocity values (allowing dynamic modulus values to be determined) . Similar laboratory tests are planned utilising AE sensors to determine AE event location, and magnitude with time. A subset of the AE data is to be analysed for source mechanisms. The data sets will be used to calibrate both the dynamic behaviour and the static strength-reduction micro-mechanics of the AC/DC models.

The tests involved the collection of ultrasonic data (both velocity and acoustic emission measurements) as well as standard rock mechanics rock response parameters. The data set provides an improved understanding of the behaviour of these argillaceous rock types under different stress histories, particularly in terms of their ultrasonic response. This is of importance for the interpretation of data collected during in situ tests using, for example, the tools developed in the OMNIBUS project. In addition the experience and expertise gained from having designed the protocol for these tests and subsequently conducting them will provide the partner conducting these tests with the opportunity to exploit them in terms of future consultancy services.
