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 this kind of analysis in Plaxis? If so, anyone could…
Displacement vs different time does not match in tutorial 8
From tutorial 8: construction of a road embankment, create curves of displacement uy and time. At the first consolidation (phase 2), the time interval is set at 300 days and 20 days to compare. The question are:
- Why do 2 curves not match each other…

Please , can any one help me how to model Accrapods or tetrapods in plaxis 2d ?
Non zero cohesion and tensile strength
Is there an official Plaxis reference or literature reference supporting the use of non zero cohesion and tensile strength (eg 1 kPa), to improve numerical calculation?
Reduction of soil suction limit (Psiunsat) leads to slower groundwater flow in unsaturated slope
I am simulating the process of pipe burst induced groundwater flow in an unsaturated slope (see simplified sketch in Figure 1 below). According to the according to the k-function curve, a lower limit of soil suction will make the soil more permeable at…

Tunnel _ volume strain input
Hi all, I was modelling the volume expansion (due to temperature change) by inputting the volume strain of material directly. But when I consider the tunnel, I cannot input the volume strain value to the lining ( plate material), so it shows the wrong…
lateral soil slippage at the sides of the pile
Hello,
Can anyone please help as how can I model " lateral soil slippage at the sides of the pile" using embedded beam in PLAXIS.
Thank you,

water pore pressure
hello. I want to ask, previously at this time I was modeling soil improvement using the PVD method with preloading, but when I saw the pore water pressure output in the middle of the soft clay layer the result was like this. if it's like this why is my…
Plaxis Python API - Change parameters of soil materials
Hi,
I am trying to change the soil parameters of a soil already present in the Plaxis Model using Python and V22 (new material database).
How do you have to address the parameter in order to change the value? For example, if I try to change E50Ref…

The E50 in the hardening soil model（HS）when using the "soiltest" in PLAXIS 2D is different from the input value
Dear all,
When using “Triaxial test” of the “soiltest” option together with the hardening soil model in PLAXIS 2D, input the parameters as Figure 1 and get the parameter E50 from Figure 2 according to the definition in Figure 3, then it can be found…
Error 111
Hello,
I am attempting to model a plate subject to an upward imposed displacement in a soil mass with two soil layers (see figure below). I activated the plate, the displacement and both soil polygons and then started the calculation.
This resulted…

Initial void ratio, einit and Cc, Cr value
Hi all,
In Plaxis, the term initial void ratio is defined as eo or the void ratio represent the OBP of the soil? I think it should be eo as consolidation settlement equation relating Cc and Cr depends on the eo, therfore Is any way to calculate…
How to prevent two polygons from merging as same soil/material in python API? Seems that when you add a different polygon on top of an already existing polygon, Plaxis automatically assigns a soil material of the polygon underneath?
As further description to the title, it seems in the python API when you add a polygon on top of an already existing soil polygon, when you run a gotostages or gotoflows function, the soil/material assigned to the smaller polygon (yellow below) in the…
Is it possible to model randomly oriented, short, discrete fiber reinforced clay soil using Plaxis 2D?
