Plaxis does not include in the Soil Test tool the pressuremeter test. I have some pressuremeter tests resutls and I would like to estimate the geotechnical parameters from the soil with them.
As the soil test tool does not have this test any idea? Could I do an axxysimterical model and apply a horizontal distributed increasing laod at the pressuremeter test depth in order to simulate the test?
Kind Regards
Hi there,
The Pressuremeter test has been available in SoilTest in 2D for a few years. However, the Pressuremeter test is only available for the Hardening Soil model in drained conditions, and it may be used to simulate the pressuremeter response considering volumetric strain up to 40%. For more information, please refer to Chapter 11.10.7 of the PLAXIS 2D – Reference Manual.

In theory, you can also set up an axisymmetric model in PLAXIS 2D or a full 3D model in PLAXIS 3D, where you apply lateral pressure to the soil resulting in the deformation of the borehole wall.
Just to add a follow up question to this topic - how can a stress-dependent test be selected? In the reference manual it is stated that the user can model a stress-controlled or strain-controlled test using the SoilTest tool, but it is not possible to select the stress-controlled option since the drop-down menu is inactive.
Thanks in advance!
