ANALYSIS AND MODEL STUDIES OF UNDERGROUND OPENINGS IN JOINTED ROCK. RESEARCH ON ROCK BOLT REINFORCEMENT

PROGRESS IS REPORTED IN A CONTINUING STUDY OF BEHAVIOR OF UNDERGROUND STRUCTURES IN JOINTED ROCK. THE FIRST PART DISCUSSES FINITE ELEMENT METHODS USED IN MODELING THE NONLINEAR ASPECT OF JOINT BEHAVIOR IN A COMPLEXILTY JOINTED ROCK MASS. THE METHOD IS THEN EXAMINED CRITICALLY BY APPLYING IT IN A COMPUTER SIMULATION OF A PHYSICAL MODEL STUDY (BLOCK MODEL CONDUCTED BY DR. LYNDON ROSENBLAD IN THE MISSOURI RIVER DIVISION LABORATORY). FINALLY THE PROBLEM OF SIZE EFFECT IN TUNNELS (NON-LINEAR SCALING OF TUNNEL STRENGTH) IS ATTACKED BY THE FINITE ELEMENT METHOD AND BY PHYSICAL MODEL STUDIES USING A CENTRIFUGE. /AUTHOR/
