Publisher Summary

Engineering rock mechanics is concerned with the response of rock to an engineering, man-induced disturbance, and is different from geological rock mechanics, which deals with disturbances caused naturally by folds, faults, fractures, and other geological processes. Engineering rock mechanics is an interdisciplinary engineering science that requires interaction between physical, mathematical, and geological sciences and civil, petroleum, and mining engineering. The present state of rock mechanics knowledge permits only limited correlations to be made between theoretical predictions and empirical results. Therefore, the most useful principles are based on data obtained from laboratory testing and in-situ measurements, used in conjunction with the basic concepts of solid mechanics to quantify the behavior of rock in response to various disturbances. There is an increasing focus on in-situ measurements, because rock properties are considered as site-specific; that is, the properties of a rock type at one site can be significantly different from those of the same type at another site, even if the geological environments are similar.
