STATIC AND DYNAMIC STRESSES IN SLOPES

THE CHANGE IN THE INITIAL STRESS PATTERN IN ROCK DUE TO LOADING OR EXCAVATION IS INVESTIGATED BY THE FINITE ELEMENT METHOD OF ANALYSIS. A METHOD IS ALSO PRESENTED FOR EVALUATING THE DYNAMIC STRESSES CAUSED BY AN EARTHQUAKE. THE METHOD OF ANALYSIS IS NOT RESTRICTED TO THE SOLUTION OF STRESSES IN SLOPES. IT CAN ALSO BE USED TO DETERMINE THE STRESSES AND STRAINS DUE TO UNDERGROUND EXCAVATION OR THE DRILLING OF BOREHOLES. RESEARCH IS UNDERWAY AT THE UNIVERSITY OF BRITISH COLUMBIA ON TWO PERTINENT POSSIBLE EXTENSIONS OF THIS METHOD WHICH ARE TO ROCK MECHANICS: EXTENSION OF THE DYNAMIC ANALYSIS TO INELASTIC MATERIAL AND THE DEVELOPMENT OF A CREEP-STIFFNESS MATRIX FOR THE SOLUTION OF FLOW PROBLEMS. IF A SUITABLE CREEP-STIFFNESS MATRIX CAN BE OBTAINED, THEN NOT ONLY THE CONTINUING CREEP DEFORMATIONS OF ROCK CAN BE ESTIMATED, BUT ALSO THE CHANGING STRESS PATTERN DURING SUCH DEFORMATIONS.
