Am trying to model the effect of thermal loading on the backfill behind integral abutment by using Plaxis 2D. I modelled the concrete bridge deck as Linear Plate element and provide a prescribed displacement near the top of the abutment. The applied displacement…

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?

Hi, how can I use the Python API to model tunnels? I'm already going crazy! If I use the process of Tunnel Designer to code and model, the code will terminate when assigning material to the tunnel plate unit, and the error is' The plate unit does not…

Hello Everyone! Currently I'm trying to figure out how does work example programs from this topic: https://communities.bentley.com/products/geotech-analysis/w/wiki/45468/creating-user-defined-soil-models After several tries I've downloaded and started…

Hi Everyone, I am trying to use the Sigma/W software to model stress and settlement distribution for an embankment over soft soils with geogrid reinforcement. Currently I am modeling the geogrid with a beam element, similar to geostudio's approach to…

Hi all! I am wandering that PLAXIS 2d is able to do the plate loading test for shallow foundation or not? Lack some literatures for this. I want to know how to do the loading test by adding some loads to the foundation and how to find the ultimate bearing…

Hi, I'm making a base for a lattice mast in Plaxis 3D. The foundation takes the loads from the mast at four points. What is the best way to make bending moments Mx, My, Mz at all points?

Hi, I am a civil engineering student and am trying to model a reclamation project with Plaxis-2D. I was trying to study the lateral deformation caused by wave loading on the artificial island, but since the boundaries are fixed, no lateral deformation…

Which of the following will be the best-suited soil model to study the shear strength gain from the ground improvement by prefabricated vertical drains? Can anyone compare the Modified Cam Clay (MCC) model and Soft Soil Model to find the better one for…

Hi All, I am working on the analysis job for an excavation work? So far I have proceeded to the completion of excavation that has been temporarily supported by struts? I am about to activate the ground floor level slab and deactivate the struts…

Hi everyone, I am working on a simple excavation and lateral support problem with soil berm as support for intermediate stages before reaching the final excavation level. For the last stage of soil berm removal before reaching the final excavation level…

Hi, I am a civil engineering student and am doing a project that requires the simulation of deep mixing columns in a reclamation plan. I have built the model, but my supervisors told me that I have to define the boundaries between the soil and the DCM…

Hi, I am a civil engineering student and am doing a simple analysis of a reclamation plan on Plaxis-2D. I wanted to know the deformation of the plan and tried to do so by setting the boundaries (highlighted in red) as "free line displacement". However…

Hi, im doing a dynamic analysis of an earth dam and I am a little confused of the boundary conditions I need to use because as you can see in the figure my model is moving like a rigid solid. I create a Line Displacement in the bottom with my Displacement…

Hi, I am doing pseudo static analysis in earth dam to calculate the yield acceleration for different geometry and property configurations. I have questions about the boundary conditions to calculate this value, because my ky_crit change depending if my…

Hi, I am trying to evaluate the slope reinforced by a row of piles under dynamic conditions (earthquake data). I want to obtain maximum lateral displacement v/s dynamic time under lateral loading condition. So what should be the boundary condition of…

After the model is picked in a manager, the corresponding module doesn't start. I can check that the installation of program and dependencies went well. Is it an usual issue and is there a fix before I reinstall operating system. I can't really be…

Hi, I modeled and embedded beam row in plaxis and simulated groundwater drawdown using steady State flow analysis and setting ground water heads at the extreme boundary and excavation level. I noticed that I was getting a little bit of heave behind…

Hi All, Is it possible to model open ended steel sigma "Σ" pile sections or PFC sections in Plaxis 3D?

Hi Dears, I have tried many way to excavate or add a plate at a certain depth in plaxis to simulate the embedement depth, but none of them gave a reasonable answer. Is there any one can help of how to embedded a foting in Plaxis 2d? I could not…

Hi all, Can anyone share some screenshots showing the soil arching effect in the retaining system or embankment pile support in Plaxis 2D for study purpose? I did a sample model but couldn't get that effect. Plaxis 3D ==> From…

Dear all, I am in the process of doing an analysis of the stability during installation of an offshore monopile in PLAXIS 3D. For this analysis, I am using the HSsmall model for the sand layers. For this analysis, I have the following setup: - A monopile…

Hello Plaxis Community, I am currently making a 3D model for a 7 story building on one basement level founded in soft clays. My project is surrounded by sheet piles driven into the clay to retain the water table which circulates in the sands…

Hello, So i'm having fun with PLAXIS 3D, I have this structure which is a 3D rectangle made of steel. I got a load resultant with Vertical, Horizontal, and Moments at the geometric center located at the base z=0, point B. Point B is located at…

Hello everyone, My first question here in the forum! I'm modeling a set of foundations on weathered granite and I'm using the Hoek-Brown (HB) model. Everything in the material model works perfectly fine, however, three questions regarding the material…
