Hi Plaxis Users, I have a point cloud of pore pressure obtained from another program/analysis that I want to use in PLAXIS 2D. Do you know what would be the best way to do it? Thanks!

Hi everyone, after running the "safety" calculation for the default number of steps (100), it didn't stabilize the Msf, so I extended it to 400 steps. It stabilized the FoS to around 2.6 for about 100 steps, while the lateral displacement I was monitoring…

Hello everyone I wonder about the meaning of the Maccel value. I checked the Plaxis 2D reference manual and it says "The value of this parameter is always 0." Why it's always zero and what does it do? Thank you

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…

Hi Why does lifting occur when filling a Dam reservoir?

Hello everybody, I'm trying to programm a simple Plaxis routine to run my model and generate results such as deviatoric stress vs axial strain, pore pressure vs axial strain, among others. The thing is that i cannot find where those names are. I…

Greetings, I conducted stability analysis of deep excavation at the final stage using Plaxis 2D analysis. The excavation depth is 15 m while the penetration depth is 12 m. When performing stability analysis, the plate element (diaphragm wall) has a large…

Hi I am finding these weird high localized deformations in my outputs and I want to know what is going on. It is important to mention that I turned off the Arc-length control type option to make my model works. I hope you can help. Thanks in advanc…

Hello, I am doing an axisymmetric 2D analysis using Plaxis's Flow Only option to calculate total discharge at the bottom of a 42 feet circular shaft. But Plaxis is giving me the following error: Errod Code: Ultimate state not reached in groundwater…

Hi all, Anyone please explain about the POP , why this diagram differs with OCR and in which instance use POP? Can use both OCR and POP at the same time or any conditions are there? Thanks, Nitha.

I've a wall in tension that should be in compression. As shown in the screenshot below I've a symmetric model where the excavation is conducted in 2 steps, removing half of the bench on the left & installing the wall then excavating the right half &…

Hi all, The material model stated that Eo is needed to be used for the soil with high linear elastic region and E50 for all loading cases and Eur for the problems like excavation and tunneling. My question is if the deviatoric loading is in the linear…

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…

Buenos días para análisis geotécnico en construcción de terraplén en zonas tropicales con nivel freático a nivel de terreno realice simulación por plaxis para determinar asentamientos los materiales empleados en terraplén son (A-2-4, A-4, 4-6 y A…

Hi all, The heave of the deep excavation in weak clays due to self-weight will be influenced by the depth of embedment of the wall as shown below. Since the stiff wall we can take as the bottom but the flexible wall the heave influence reduces…

Hi all, I try to model the RC retaining wall using linear elastic non-porous material for RC retaining wall in the soil with c=o and phi =30. The construction sequence adapted as shown below. Initial condition : Construct retaining wall and…

Hi there, My university already has a licence for plaxis2D, but I need the Barcelona basic model (BBM) dll for the soil and water coupling phase. Can you share with me the "Barcelona basic model (BBM) dll" for plaxis 2D? Cheers,

Hi all, When doing an axisymmetric excavation, please how to provide water table (assume initial water table at the top surface? (for this project need to check the full water condition on the retained side so can't use steady flow for water table)…

Hi all, To calculate the ks, we can provide prescribed displacement of 25mm on the footing in Plaxis 2D and get the bearing pressure for that and calculate the ks. I have some questions regarding ks. 01. Based on the Bowles equation, he requested…

Dear Guys, First of all I am new to this forum. I never knew such a forum existed. I am modelling a steel supported braced excavations (struts). In the project the diagonal struts in the corners are 20 metres long while the horizontal (located at…

Hi all, I have a memory to read in the reference manual, even though the plastic analysis has time option to provide in the analysis but that time doesn't considered in the analysis. So if I want to cut a unsupported slope in the cohesion less soil…

Hello, I am modeling a battered (5 degree) wall with ice force as a point load acting on it. The ice load is activated in the final phase of the input and runs successfully but when checking the output I notice that the ice load doesn't show up (not active…

Hello there, I was trying to predict the settlement of layered soils due to the groundwater lowering. My guess is that, in order to model the consolidation process, I need to apply a flow function, modelling the hydraulic head lowering over time,…
