NATM Tunnel Analysis in Plaxis 3D calculation error
I am doing a NATM Tunnel Analysis in Plaxis 3D, but when everything is finished and the calculations are given, it shows a problem in phase 01 like this. (Soil body seems to collapse. Please inspect Output results. [Error code: 101] ) What is the reason…
gINT alternative in OpenRoads Designer
Hi,
I am a geotechnical engineer and I am using Openrails and OpenRoads designer. Our company has a license for both software, but no license for gINT toolbox. I wonder if there is any possibility to substitute gINT with some tool that does not need…
A problem retrieve data from soiltest by python
Hi,
I developed a code below to retrieve data (Shear_strain_xy & Shear_stress_xy) from the DSS test of the Soiltest module in Plaxis 2D Ultimate (academic version). This code was already working, but after upgrading to the latest version of Plaxis …
Do we have a database sample for AGS 4.1 for the gINT?
Do we have a database sample for AGS 4.1 for the gINT?
Well foundation Sinking
Hi
Is there any possibility to check well sinking analysis in plaxis??? How to incorporate the reduction of skin friction due to the projection in well curb and dredging action?????
Geo Question=> OCR and PI (Not Plaxis related)
Hi Geo community,
If anyone know how OCR and PI affect the engineering properties of soil like elastic modulus, cohesion and friction angle of the soil, please share.
Thanks.
Modelling of volume pile
Good Morning Sir,
I am modelling my concrete using volume element in PLAXIS 3D. It is easier to get shear force and bending moment through this modelling. We can get the bending moment and shear force along the length of pile using cross section curve…
Breakwater
Please , can any one help me how to model Accrapods or tetrapods in plaxis 2d ?
Deriving soil hardening model parameters - drained vs undrained tests
Hi,
I'm scheduling triaxial tests on silty sand (SM) and while I understand that consolidated drained (CD) test is required to obtain the soil hardening parameters, the test may take a long time due to the fine content in the soil sample. Therefore…
Plaxis plot output python: setting the plottype doesn't update in the exported figure.
I am trying to export plots for structural elements. In one case i prefer to have a distribution plottype instead of deformation. Setting the plottype from python does result in a correct command in the plaxis command lines, however nothing happens. Only…
Excavation with no drop down in water level
Dear Sir,
I have an excavation model in Plaxis 2D with SBP wall at both sides. We have proposed recharge well on site to prevent the water level drop down. Therefore, In Plaxis model, I defined the pore water calculation type as "phreatic line" with…
how to model a cavity in a soil
Hi, For my master these, I study the influence that a cavity has on the surrounding ground (decompression vault) and also on a tunnel. To model the cavity, I assigned it an elastic behavior with a very low elastic modulus (10^-6), Poisson's ratio and…
Inclination Angle Vs Strength in Soil Nail
Hi all,
Does anyone know the reason why the inclination angle of the soil nail with horizontal 10 to 20 degrees is effective and if we increase the angle, strength is not effective and tension changes into compression?
Thanks.
Sigma/W: Modeling an embankment on soft soil with geogrid for basal reinforcement
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…
Importing Geotechnical data into ORD using an excel file.
Hello there.
I am currently working in the geotechnical ribbon workflow. I have an excel file of all the information needed for the required Borehole tab (e.g., Easting , Northing , Elevation , and Hole Depth ). Also, in the excel file I have the l…
Shear strength profile at a line cross section?
How can I create a profile of shear strength along x direction at a particular depth of my soil model (MCC) in PLAXIS 2D?
Consolidation or Fully coupled flow deformation for excess pore pressure variation due to line drain
Which of the above analyses is better for finding the variation of excess pore pressure with radial distance from a line drain?
Boundary conditions in the case of a pseudo static analysis
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…
The related problems of controlled caisson
As shown in the picture, I am simulating a suspended caisson, and I want to obtain a suspension force that will keep the caisson stationary at any depth. At present, my method is to add line displacement at the bottom of the caisson, but if I specify…
Why my question does not appear when I ask?
I sent you many questions but I could not see my questions in the list of questions.
Plaxis LE extrusion
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?
Soil Mechanics with ADINA
Soil Mechanics with ADINA
ADINA is used widely in many fields of applications, including the field of geomechanics. Currently, ADINA offers the following geotechnical material models: Drucker-Prager, Mohr-Coulomb, Cam-clay, and a curve description model…
Soil Consolidation Analysis
Soil Consolidation Analysis
We present a typical problem in soil consolidation analysis, in which we compute the distribution of excess pore pressure and the displacement under the applied load for a simple three-layered soil model.
The above animation…
