It is our pleasure to invite you to the second edition of this symposium. Last year, more than 60 people attended the first edition which was organized on Zoom, due to CoVid issues. We hope and believe that this year we’ll be able to welcome you in person at HEIA-FR, in order to practice hands-on exercises. Anyway, you will have the choice to participate physically in Fribourg, or virtually, via Zoom.
Uncertainty is present everywhere in geotechnical engineering and soil-structure interaction analysis: soil parameters are usually not known exactly, and also vary in space. The common practice consists in performing a deterministic analysis with "safety" factors. However, this technique does not give much insight into what the actual risk is. Today, stronger integration of probabilistic approaches into safety assessment procedures and geotechnical computational mechanics, in general, seems appropriate.
This short course will give participants an insight into probabilistic approaches, uncertainty quantification, reliability, sensitivity analyses and associated benefits with respect to a deterministic approach. Practical applications including typical geotechnical problems (slope stability, foundation bearing capacity, anchored wall, and tunnel in urban environment) will be discussed and solved using UQLab (www.uqlab.com) and ZSOIL (www.zsoil.com).
