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…

I am very glad to write this post because last time I got a benchmark problem regarding embankment consolidation problem over PVD-treated soft soil " Comparison of Drainage Line Elements in PLAXIS 2D and 3D.....". After that, I successfully published…

We are doing independent check / PE review of an deep excavation project, which majority of the excavation are in Rocks. The designer used Hardening soil model to model the Rock layers. My questions are: 1. is it proper to use HS model to model the…

I am aiming to simulate a deep excavation near an existing tower with 4 levels of below grade parking (shaded in grey). The approximate loading of the building is 10 ksf. Therefore I have simulated the material (shaded in grey) as a non-porous Mohr Coloumb…

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…

Greeting for everyone, I use Plaxis 3D to simulate deep excavation using Butress wall and Cross wall. However, when I activate interface in the early phase (using very small Rinter value), the severe divergence occurs in the output results. Is there…

Hi there I am trying to model a deep excavation in unsaturated conditions. As I only have suction measurements during dry and wet periods, I have been trying to input then as pore-presure in the user-defined water condition of certain clusters (clay…

Hi all, If anyone know how to decide the spacing between the instrumentations which are needed to provide on site to measure in-situ data like ground settlement markers, prism markers, water stand pipe, piezometers, inclinometers etc. Thanks.

Hi all, In the sheetpile deep excavation seepage is possible which induces hydraulic failures. In the surface of the cohesion less soil at the exit position of the excavation there will be a boiling and we can find its FOS using ic/iexit. I need some…

Hi all, Anyone, please tell how to estimate the influence zone during the deep excavation (this helps to check whether the surrounding buildings affect or not and then can do impact assessment). I got these details from one paper. Thanks.

Dear All, Im facing a problem about assigning the parameter of pipe pile wall with strengthening H-pile and Plate in my Plaxis 3D (Plate element) Section is shown as below: the spacing is 800mm centre to centre and bending in strong axis. How…

Good morning, I am simulating a deep excavation using Plaxis 2D. I used fixed end anchor to simulate the struts. In the output, The N force in the struts is the real force I take, or I should divide it by the spacing between struts in the out of plane…

Hi, I am building the ELS model in Plaxis 3D. I am wondering what form (beam, node to node anchor) should I apply for the strut, which required to preloading. (I think it should be node-node due to prestressing) But there are 2 diagonal struts connected…

We posted the recording of our November 2019 SIG on Excavation Dewatering and Common Pitfalls in PLAXIS 2D and PLAXIS 3D on the Bentley LEARN server in the Geotechnical Learning Path: https://learn.bentley.com/app/Public/ViewLearningPathDetails?lpId=113626…
