A HYDRAULIC TRIAXIAL APPARATUS FOR CONTROLLED STRESS PATH TESTING

A simple and versatile hydraulically operated triaxial apparatus has been developed for stress path testing. The apparatus is described and the range of tests which can be performed is discussed. These include both stress controlled and strain controlled tests. Some typical test results are presented and are used to illustrate the fact that under undrained conditions the deformation of the sample is A function only of the magnitude and sign of the stress difference, and is not otherwise influenced by the absolute magnitude of the total stress changes. The apparatus can be used with any convenient pressure control and recording system. A simple adaptation of the self-compensating mercury control system is illustrated. (A). /TRRL/
