Online by Zoom from HEIA Fribourg Switzerland,
Friday 27.8.2021 09.00 – 17.30,
Organised by Zace Services Ltd, Geomod Ltd & ITEC-HEIA Fribourg
also celebrating 36 years ZSOIL.PCca

Registration is open now: Registration form

A special accent is put this year on Uncertainty Quantification and Reliability Analysis.

Numerical simulation in geomechanics, constitutive aspects, soil-structure interaction and associated structural analysis with emphasis on present and future engineering practice: theory, applications, case studies, failure analyses, optimisation, probabilistic approaches.

The symposium combines invited presentations, and contributions by ZSOIL users and others. It has been taking place every year in late summer over the past fifteen years, at the Swiss Federal Institute of Technology, in Lausanne and newly at Haute Ecole d’Ingénierie et d’Architecture de Fribourg.


9:00 – 12:00
Invited Lecture: S.Marelli, ETHZ
An introduction to Uncertainty Quantification and Reliability Analysis in Geotechnics.

S.Commend & G. Jacot-Descombes, HEIA Fribourg & Geomod SA.
Reliability analyses applied to day-to-day geotechnical engineering using meta-models: analytical, 2D and 3D numerical examples.
Marc Groslambert & al. Geomod SA.
The Bayesian inversion and reliability analysis in geotechnics with ZSOIL.PC & UQLab.
Marc Groslambert & al. Geomod SA.

Engineers and developers confronted with the need to perform accurate numerical simulations or optimisations for complex underground, above ground or combined constructions have an opportunity to exchange experience, see state of the art presentations of recent case studies and get a comprehensive introduction to numerical simulations in 2D or 3D, in particular with ZSOIL.PC, in dry or partially saturated rock or soil,with full structural capabilities, soil-structureinteraction, interfaces, thermal effects, ultimate load evaluation, continuous safety assessment, including creep, swelling, dilation, dynamics etc.

UQLab is a computational framework for uncertainty quantification which makes uncertainty quantification available to anybody, in any field of applied science and engineering.
UQLab is developed at the Chair of Risk, Safety and Uncertainty Quantification of ETH Zurich under the supervision of Prof. B. Sudret and Dr. S. Marelli.

is a user-friendly 2D/3D finite element package for soil, rock and soil-structure analysis available and used worldwide since 1985, and continuously upgraded. The program was developed at Zace Services Ltd, by a team of engineers with research experience at the Swiss Federal Institute of Technology in Lausanne, UC Berkeley, California Institute of Technology, Purdue University, Cracow University of Technology, and Stanford University . The aim is to provide civil engineers with a simple tool to accurately support geomechanical and structural engineering analysis, dimensioning and optimisation. Since ZSOIL.PC first came out in 1985 it has steadily gained worldwide acceptance among practitioners as well as teachers and researchers. Today, unto ten free student versions are downloaded every day.

FEE: 200 EUR (free for speakers & HEIA Fribourg affiliates, 50% discount for ZSOIL owners,
10 EUR for students). Registration required.
