A METHOD FOR THE ANALYSIS OF STRESS IN BRITTLE ROCK

A NUMERICAL METHOD FOR THE DETERMINATION OF THE STRESSES ASSOCIATED WITH THE FRACTURE PROCESSES OF A BRITTLE ROCK MATERIAL IS PROPOSED. IT IS SHOWN THAT THE VARIOUS ZONES OF FRACTURE AROUND AN UNDERGROUND OPENING CAN BE PREDICTED AND A STABILITY ANALYSIS OF THE ROCK STRUCTURE CAN BE PERFORMED WHILE TAKING THE COMPLETE PHYSICAL BEHAVIOUR OF THE ROCK MATERIAL INTO ACCOUNT. THE METHOD IS BASED UPON THE FINITE- ELEMENT ANALYSIS AND PROCESS OF SUCCESSIVE APPROXIMATIONS. AN EXAMPLE OF APPLICATION FOR A NORITE ROCK MASS CONTAINING A CIRCULAR OPENING, UNDER THE CONDITIONS OF PLANE STRAIN AND A UNIAXIAL STRESS FIELD, IS GIVEN FOR ILLUSTRATION. /AUTHOR/
