C_ref Line contraction

I am trying to simulate the effect at the ground surface of the excavation of a tunnel. Clearly exagerating its value, I tried to perform the analysis usig a c_ref = 10% with a set value of cohesion c...
Dynamic analysis-tunnel lining

Hello, I am running a dynamic analysis model in Plaxis to find a vertical displacement of the pipeline in liquefiable soil, but it takes one day and is still running in 11.21 seconds. Is it normal for...
Prescribed Line Displacements on Vertical Plate in PLAXIS 3D

I am applying line displacement along part of a vertical plate at the top to model an integral bridge. During the expansion stage I model prescribed displacement at the top of the plate along a certain...
What should be the weight of tunnel lining in kN/m/m?

suppose I am using 25 kN/m3 of unit weight of concrete and the unit weight of soil is 19kN/m3 and modelling lining as a plate element. Should i subtract the unit weights and multiply with the thickness...
I am modeling a foundation on rock and wish to extract the resulting bearing pressures (Sigma yy) at the base of the footing. Should I plot draw the line cross-section directly under the plate element...

The foundation is modeled as a plate element having the following properties: EA = 59450820.01 kN/m EI = 19816940 kNm2/m w = 26 kN/m/m (considering a unit weight of 24 kN/m3 for the underlying rock and...
