    Abstract

    In order to simulate pressuremeter testing in soft rock, a series of detailed model tests were undertaken under carefully controlled conditions in the laboratory. The technique employed made use of a modified triaxial cell in which thick walled cylindrical specimens of a synthetic soft rock, subjected to constant external confining pressures, were tested to failure. Pressure was applied in increments to the internal cavity, and measurements were made of cavity and specimen volume changes under fully drained conditions. This paper describes the pressuremeter simulation tests, giving details of test techniques and results.
