Generation of curve between displacement and normal stress for the node of interface element
I am extracting load displacement curve considering every step. But right now I am considering node corresponding to the soil.
Similarly, I want to plot the curve between two axes which will be having displacement of node on x axis and corresponding…
Medel piled raft foundation with volume pile + plate element (for lateral loading)
Dear All
I have modeled piled raft foundation which piles modeled as volume pile while raft modeled as plate element. To simulate soil - structure interaction, I created interface to both raft and piles.
In my understanding, correct me if I'm wrong…
Picos [204] incorrect solution, slow convergence when boundary and flow conditions are changed in PVD installed soil
I wanted to create a graph of excess pore pressure vs radial/horizontal distance for an MCC soil model at a particular depth installed with prefabricated vertical drains. To simulate the effect of smear, transition and undisturbed zones around the PVD…
Line drains and varying permeability in the horizontal direction in a soil model
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…
Can I assign the value of skin friction to surface in Plaxis 3D
Hello everyone, I'm trying to simulate the installation of shaft sinking by adopted procedure from kinematic mechanical model, but I'm struggle with the skin friction at the wall of shaft. Can I assign the value of skin friction directly in the surface…
"Intersection failed with this error: TriangulationFail
Hello, I used the Surface option in the Borehole to create top surface matching with the Filed data from the Laser image in .dxf format. But the message I received on clicking the Mesh tab is as follows. "Intersection failed with this error: TriangulationFail…
Interface stresses
Hi,
In the table output of interface stresses there are two options 'node values' and 'stress point values'. Which one should be used to extract stresses?
Do interface has stress points as well?
The status of the points show failure or failure…
Failure of interfaces not working how I expect
Hi,
I am doing my undergraduate thesis on soil nail walls and I have a question about the failure of interfaces. I have derived the strength of the interfaces based on the soil using an Rinter of 0.67. The soil properties are based on the Mohr-Coulomb…
Pile as volume element (skin and base friction) on plaxis 3d
Hello, i want to create a pile as a volume element. ive created an interface but im not sure how to simulate the skin and base friction with the interface. Can anyone help me plase? Thank you :)
Providing interface to cylindrical volume Deep Mixed column
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…
Floating windfarm anchor pile 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,…
p-y curves as interface in plaxis 3D?
Dear All,
Can we input p-y curves as interfaces for pile in Plaxis 3D?
During time history analysis, instead of the R inter value, is there a way we can input p-y curves in the interfaces?
How does one overcome this?
Unrealistic peak interface stresses in Plaxis 3D
Hi All,
I am currently working on a cross passage excavation between two TBM tunnels. The cross passage, its collar and the TBM tunnel are shown in the following figure.
The volume loss inside TBM tunnel is modelled by using surface loads (30…
How to model contact that only transfers axial compression but no axial tension and shear in Plaxis?
Hi guys,
How can I model this type of contact between surfaces? Thanks for the help.
How to get Rinter value
Referring to the question and answer about Rinter ( https://communities.bentley.com/products/geotech-analysis/f/plaxis-soilvision-forum/212033/rinter-value )
We typically do not recommend parameter values as this should be based on data collected…
Validation of tension pile
I am trying to validate a small-scale rough tension pile embedded in sand using PLAXIS 3D. I am using a volume pile with the linear elastic constitutive model for concrete and sand with MC constitutive model. The volume pile was modeled with an interface…
how to correctly provide pile head connection while modelling a piled raft foundation?
Here raft is modelled as a volume element and piles as embedded pile element, and a negative interface is given between raft and soli. Please kindly help as the results are coming same for the pile head connection condition.
