IDENTIFYING SOIL PARAMETERS BY MEANS OF LABORATORY AND IN SITU TESTING

If the use of in situ tests for determining soil parameters has been widely developed in the case of empirical relationships or simple models such as the elasticity or perfect plasticity, it is not sufficiently applied when dealing with an elastoplastic model. In this paper a methodology for identifying the parameters of an elastoplastic model based on the interpretation of laboratory and in situ tests is presented. An inverse method was used to extract several parameters from pressuremeter tests, while triaxial and oedometer tests were used to complement the whole set of parameters. This method has been tested by computing vertical settlements of an embankment on soft clay. The very encouraging results obtained here provided a preliminary validation of this method. (A)
