Dear All,
I have a Plaxis 3D model in which the ground surface is a slope replicating the real topography (modelled using point cloud). Is there a way to assign E' and c'/Su increase with depth (not with level) in the Plaxis 3D model? Assigning E' and c'/Su increase with level for a slope generates unrealistic soil properties for soils in the bottom part of the slope if level (Zref) is choosen say at mid height slope.
Thank you.
Kind regards,
Victor
Dear Victor,
It is possible to have E', c', and Su increase by the depth in Mohr-Coulomb soil model. You can go to advanced option in soil parameters input. In Hardening Soil, you can also use the strength increase by the depth using this way.
Hi Ari. I am affraid this works only when you have a flat ground / strata level. If you use this option in a model with sloping ground / strata then you will obtain overprediction of soil properties for soils in the bottom part of a slope if Zref is choosen at mid height of slope.
