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…

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…

On Calibrating PM4 models, how to generate g/gmax vs strain graph and damping vs strain graph, using soil testing to adjust the secondary parameters.?

Why liquefied points are observed in soil while using advanced constitutive models PM4sand and PM4silts before seismic loading? The liquefied points were observed in static phase only

Please , can any one help me how to model Accrapods or tetrapods in plaxis 2d ?

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?

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…

I am trying to simulate the effect of the installation of PVDs on soft soil (soil model used: MCC). The installation of PVD (in this case, a line drain) causes disturbance to the soil and creates three zones around the soil. A smear zone, a transition…

Hi, I extruded the model from Figure 1 and the problem in Figure 2 appeared. I did in the interface of Plaxis LE, what happened?

Hello, I have been wondering a little on the modelling of undrained behavoir in clays using the Hardening Soil Undrained A model, especially with regards to the prevalence of anisotrophy of clays in undrained loading. In order to model this behavoir…

Hi all, In the retaining system in sloping ground, the sloping angle is included in the soil pressure through the lateral coefficient and the depth is considered from the top of the retaining system not the top of the sloping ground. My question…

Dear All, Maybe the following questions are the basic ones but I couldn't figure them out correctly so need your help to solve my doubt. Questions => 1. Why soil parameters that are inserted in any checking or Plaxis analysis should be measured…

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…

Hello guys, Is there any way I can use soil data from the SoilVision database in the Plaxis LE API? Thanks for the attention!

Hey everyone, I want to ask about transformation of curves from dynamic time to frequency domain in plaxis 3D because I need it to calculate impedance functions ??

Hello. I am new to PLAXIS 3d V21. I have been learning PLAXIS 3D V20 which seemed to be much simpler than the current V21. I wanted to design a shallow footing setting on the ground surface. I want to measure the bearing capacity of the ground and…

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, Faisal

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…

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…

Hello, I am doing PLASXIS 3D analysis for the Deep Mixed (DM) column installed in soft soil under the embankment load. DM columns are made by extruding a cylindrical volume and replacing the soft soil material with the DM column material. The soft soil…

When inputting values of soil.I have questions about the accurate relation between G0, Eur and υ. When changing the value of Eur to 1, it will say Eur>2E50 and G0 must be less than 8.33. When setting the value of Eur too high(for example,100E3), it will…

#PREdesign #Firstdesign #not-final-design Hey, I'd like to back to give additional informations about my last question. As i have already said, i'm geologist, student in M2 geosciences for energy at Paris Cergy University. For my master thesis,…
