Abstract | Real-time prediction by monitoring of the evolution of response variables is a central goal in predicting rock failure. A linear relation Omega Omega(similar to 1) = C (t(f) - t) has been developed to describe the time to failure, where LI represents a response quantity, C is a constant and tf represents the failure time. Observations from laboratory creep failure experiments and precursors to volcanic eruptions are used to test the validity of the approach. Both cumulative and simple moving window techniques are developed to perform predictions and to illustrate the effects of data selection on the results. Laboratory creep failure experiments on granites show that the linear relation works well during the final approach to failure. For blind prediction, the simple moving window technique is preferred because it always uses the most recent data and excludes effects of early data deviating significantly from the predicted trend. When the predicted results show only small fluctuations, failure is imminent. (C) 2017 Elsevier B.V. All rights reserved. |
