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…

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

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, 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…

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…

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…

I am using the precipitation function to model rainwater infiltration on a slope in PLAXIS. When inputting the q value, do I need to multiply the rainfall (q) with the runoff coefficient (c) first?

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…

I want to ask when reviewing soil improvement using PVD, why is the result of the decrease in time using my plaxis 2D when 2 m spacing is faster than 1.5 m spacing and 1.5 m spacing is faster than 1 m spacing?shouldn't pvd spaced closer should be faster…

Dear Many thanks for your information. We know that in the Plaxis, we can create constitutive model programmed using FORTRAN and implement in PLAXIS through the "User Defined Soil Model" to create our own equations for the materials. I have a question…

#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,…

Hello, My project is about construction of an embankment on subgrade reinforced by stone columns covered with geosynthetic...so i need to know what's the phases of calculation required...is it the same of the stone columns without geosynthetic? Or should…

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, 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…

hello, good day. I have a wetmuck project in an underground mine. I want to analyze, model, and simulate underground mining works. such as blasting with real contours and the correct data is there to overcome the wetmuck which is very dangerous for…

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,…

Dear plaxis users and geotechnical engineers, When using plaxis to design permanent and temporary ground anchors+bored piles in plaxis 2D, the obtained values of moment, normal and shear forces are supposed to be multiplied with the out of plane distance…

We are using Plaxis to assess the settlement of an embankment on firm to stiff clay soils in which the long term settlement is critical for an acceptable design. We are adopting the Hardening Soil Model with Small Strain Soil Model and are a bit confused…

Hello everybody, I am trying to reproduce oedometer and triaxial test with Plaxis 2D, and when I select mm units, the strains results are not accurate; for instance, a 25 mm tall specimen subjected to loads up to 800 kPa shows a maximum vertical strain…

Hi, I am wondering how it would be possible to analyse stress/strain relaxation in the CRS soil-test-facility in PLAXIS 3D? I am currently using the Soft soil creep model and used the optimise parameter function to match with the lab data. However…
