[...]... the nature of engineering rock mechanics In all subsequent chapters there are ten questions Q l 1 Define the following terms: rock mechanics; 0 engineering rock mechanics; 6 lntroduction rock engineering; structural geology; engineering geology; soil mechanics; geotechnicalengineering A1.l Rockmechanics is the study of the statics and dynamics of rocks and rock masses Engineering rock mechanics is... of engineering rock mechanics The term engineering rock mechanics is used to describe the engineering application of rock mechanics to civil, mining, petroleum and environmental engineering circumstances The term mechanics, means the study of the equilibrium and motion of bodies, which includes statics and dynamics l Thus, rock mechanics is the study of mechanics applied to rock and rock masses Engineering. .. significance of the rock mass behaviour lies in the eye and brain of the engineer, not in the mechanics I It is not always realized that the term mechanics includes ‘dynamics’,but a book title such as ’River Mechanics is correct S m l r y rock dynamics’, the topic of Chapter iial, 13, is part of rock mechanics 4 Introduction Rock Mechanics Engineering Rock Mechanics and Rock Engineering Design... distinction between rock mechanics and rock engineering When rock mechanics is studied in isolation, there is no specific engineering objective The potential collapse of a rock mass is neither good nor bad: it is just a mechanical fact However, if the collapsing rock mass is in the roof of a civil engineering cavern, there is an adverse engineering connotation Conversely, if the collapsing rock mass is... rock mass is intended to fail), there is a beneficial engineering connotation In the civil engineering case, the integrity of the cavern is maintained if the rock mass in the roof does not collapse In the mining engineering case, the integrity of the mining operation is maintained if the rock mass does collapse Hence, rock engineering applies a subjective element to rock mechanics, because of the engineering. ..
