    Abstract

    The usual way to use a pressuremeter device is to measure a pressuremeter modulus, which is correlated with the elastic modulus, and a limit pressure, which is used to find the bearing capacity of the foundation. We present a new interpretation of the pressuremeter test, which allows the measurement of the elastic shear modulus by the application of an unload-reload sequence in the experimental pressuremeter process and the determination of the angle of internal friction for granular soil by the application of an elasto-plastic theory. This new method is accurate and validates the use of the pressuremeter tests for the mechanical characteristics determination, for slope stability analysis, retaining wall and tunnel design. It is used in this paper for the design of a diaphragm wall of Lyon underground.
