![]() c' and phi')? In which case the undrained shear strength derived by Plaxis in the following stages might differ from the field results. Would it be better to use undrained behavior combined with effective parameters (i.e. I'm wondering if the calculation yields reasonable results, given that Plaxis only has the undrained shear strength (hence it has no way to derive effective parameters, and using 'Ignore undrained behavior' would have here no effect). The first stage of the calculation is a gravity loading in order to establish the in-situ stresses. ![]() the input I gave is cu (from vane shear tests) and phi=0° but I left the material behavior as drained. I'm modelling the clay layers with undrained Mohr-Coulomb, i.e. The soil is mostly fill material above thick layers of soft clay followed by non-cohesive materials (such as sand). ![]() I'm using Plaxis to model a sheet pile wall between a quay and a future railroad. ![]()
