THE "DOORSTOPPER" AND TRIAXIAL ROCK STRESS MEASURING INSTRUMENTS DEVELOPED BY THE CSIR

A NUMBER OF PREVIOUS PAPERS ARE SUMMARIZED WHICH HAVE DEALT WITH VARIOUS ASPECTS OF ROCK STRESS MEASUREMENT BY MEANS OF ELECTRICAL RESISTANCE STRAIN GAGES BONDED INTO BOREHOLES. WHILE MUCH OF THE INFORMATION ALREADY HAS BEEN PURLISHED, ITS COLLECTION INTO ONE DOCUMENT COMPRISES AN IMPORTANT CONTRIBUTION FOR ANYONE CONCERNED WITH ROCK STRESS MEASUREMENT. A FULL DISCUSSION IS GIVEN OF A THEORETICAL BACKGROUND FOR THE DETERMINATION OF THE TWO PRINCIPAL STRESSES IN A PLANE BY MEANS OF A SINGLE ROSETTE GAGE BONDED ONTO THE CYLINDRICAL SURFACE OF A BOREHOLE. PRACTICAL DETAILS WHICH WOULD BE ESSENTIAL TO ANYONE INTENDING TO USE THESE TECHNIQUES ARE GIVEN TOGETHER WITH A DISCUSSION ON THE RESULTS OBTAINED IN THE FIELD. /AMR/
