THE STRESSES AROUND OPENINGS IN ROCK

THE APPLICATION OF THE PRINCIPLES OF ROCK MECHANICS TO THE DESIGN OF UNDERGROUND STRUCTURES IS REVIEWED. THE INITIAL STATE OF STRESS IN THE ROCK MASS MUST BE EITHER DETERMINED EXPERIMENTALLY OR ASSUMED. ELASTIC THEORY IS THEN USED TO DETERMINE THE CHANGE OF STRESS WHICH RESULTS FROM THE CREATION OF THE OPENING. IF THE STRENGTH PROPERTIES OF THE IN SITU ROCK ARE KNOWN, AN EVALUATION CAN BE MADE OF THE NEED FOR THE ROCK TO BE SUPPORTED AROUND THE OPENING. METHODS OF ROCK SUPPORT ARE BRIEFLY DISCUSSED. /TRRL/
