| Résumé : | In this first paper, part I, we present the elasto-plastic theory for expansion of pressuremeters in granular soil. This theory allows determination of the behaviour of the granular soil around the pressuremeter with only four mechanical parameters. It is compared with previous theory on the dataset of the pressuremeter test on Ticino sand. In the second paper, part II, we present a numerical analysis of the theoretical conventional limit pressure compared with the results of the Mohr–Coulomb non-standard model used by the Plaxis finite element program. The theoretical evolution of the conventional limit pressure as a function of the variation of each parameter shows a correct agreement with the numerical results. Conclusions are drawn on the influence of these parameters on the pressuremeter results. |
