IN SITU INVESTIGATIONS OF CREEP IN ROCK FOR THE DESIGN OF PRESSURE TUNNEL LININGS

IN-SITU PLATE-LOADING TESTS UTILIZING 1-M SQUARE PLATES WERE CONDUCTED TO STUDY THE CREEP PROPERTIES OF VARIOUS TYPES OF ROCK MASS. THE RESULTS FOR BOTH INCREASING AND DESCREASING LOAD MAY BE INTERPRETED BY THE CLASSICAL THEORY OF CREEP. A THEORETICAL ANALYSIS IS MADE OF THE DEFORMATION OF THE ROCK SURFACE WITH TIME UNDER THE ACTION OF A LOADED PLATE OF ANY SHAPE AND RIGIDITY SUGJECTED TO CONSTANT OF VARYING LOAD. THE ANALYSIS AGREES SATISFACTORILY WITH THE EXPERIMENTAL RESULTS. METHODS OF OBTAINING THE CREEP PARAMETERS DIRECTLY FROM IN-SITU TESTS ARE GIVEN. THE SECOND PART OF THE PAPER GIVES AN ANALYTICAL SOLUTION FOR THE STRESSES IN AN ELASTIC LINING OF A PRESSURE TUNNEL IN ROCK WHICH CREEPS. THE SOLUTION IS BASED ON CLASSICAL CREEP THEORY. IT IS POSSIBLE TO DETERMINE THE CREEP PROPERTIES OF ROCK BY IN-SITU TESTS AND TO APPLY THE RESULTS TO ENGINEERING PROBLEMS. /RRL(A)/
