Abstract

The purpose of this paper is to present a methodology for identifying soil parameters from pressuremeter tests. A viscoplastic model coupled with consolidation theory was employed. At first, a numerical analysis of parameters effects on constant strain rate tests was carried out. Then the results were used to develop a method for identifying soil parameters. The drainage conditions during the pressuremeter tests were also analyzed to explain the strain rate effect on the evolution of pore pressure and total pressure. The results showed that the model can satisfactorily describe the time-dependent behavior of soils during pressuremeter tests, and the method allowed us to determine efficiently soil mechanical, including viscous and hydraulic parameters from constant strain rate pressuremeter tests.
