Title: Coffee Corner: Geotechnical Analysis (AM) – Getting PLAXIS Calculation Results
Date: Tuesday, October 12, 2021
Time: 09:00 AM BST and 15.00 BST
Duration: 1 hour
[OCT 2021] The purpose of setting up a geotechnical Finite Element model is to learn something from your configuration, such as:
- How much settlement do I get?
- Is the construction stable?
- How large will the bending moment be in the retaining wall?
After setting up the analysis and running the calculation, it is time to inspect the results. But how do we do that, and what can we see here?
In this Geotechnical Analysis Coffee Corner, we will discuss the PLAXIS Output program and how you can uncover the results that you need for your design, including cross sections, structural results (forces) and generating curves.
Title: Coffee Corner: Geotechnical Analysis – NorSand: Liquefaction analysis in PLAXIS
Duration: 1 hour, 20 minutes
Available On Demand
[SEP 2021] Liquefaction phenomena can have devastating consequences for human life and the environment. In the recent past, some tailing dams failed due to static liquefaction.

In this Coffee Corner, we will go into more detail using this model and you will learn more about:
- Parameters for the NorSand model
- Calibration and attention points for this soil model
We will show a practical example demonstrating the triggering of static liquefaction.
