PROGRESS IN THE APPLICATION OF PHOTOELASTIC TECHNIQUES TO ROCK MECHANICS

THIS PAPER GIVES AN ACCOUNT OF RECENT AND CURRENT RESEARCH ON APPLICATIONS OF THE PHOTOELASTIC TECHNIQUES IN ROCK MECHANICS. THE PHOTOELASTIC COATING TECHNIQUE IS BEING USED TO INVESTIGATE THE MECHANISM OF FAILURE IN ROCK SPECIMENS UNDER UNIAXIAL COMPRESSION IN THE DEFORMATION OF ROCK MATERIALS UNDER LOAD, AND IN MODEL STUDIES OF MINING AND CIVIL ENGINEERING STRUCTURES USING ROCKS AND SIMULATED ROCK MATERIALS. THE APPLICATION OF THE TECHNIQUE IN THE FIELD HAS BEEN CONSIDERABLY EXTENDED BY THE USE OF THE SURFACE BIAXIAL OPTICAL GAUGE AND THE PHOTOELASTIC STRESSMETER, AND BY THE DEVELOPMENT OF A NEW SYSTEM OF IN SITU MEASUREMENT, MAKING USE OF PHOTOELASTIC TRANSDUCERS. A DESCRIPTION IS GIVEN OF SOME OF THE METHODS BY WHICH THESE TECHNIQUES ARE BEING APPLIED TO MEASURE IN SITU LOADS ON SUPPORTS AND THE STRESSES AROUND EXCAVATIONS AND WITHIN STRUCTURES IN MINING AND CIVIL ENGINEERING. /AUTHOR/
