At the very interesting workshop on soil cyclic behaviour at NGI, Norway, February this year, we had a dsicussion on building a database of soil parameters for different constitutive models for various soil types, so that the user can get an initial estimation of parameters based on the index properties, before he performs laboratory testing.Continue reading
Job description: The successful candidate will develop research in numerical modelling of soil-structure interaction under complex loadings including dynamics. Fundamental and numerical studies will be developed in relation with experimental studies performed in Laboratoire Navier and by outside partners. In addition to the development of classical techniques for numerical modelling of materials and structures (FEM, BEM, FFT, …), the valorization of big data gathered from the monitoring of geotechnical structures will be a priority area of research. This includes the development of new tools based on artificial intelligence systems for modelling and design in geotechnics.
These research activities will make use of advanced numerical methods and will be oriented towards applications to underground structures, foundation engineering, resilience of geotechnical structures, effect of multiphysics couplings on the behavior of geomaterials (partial saturation, thermal effects, …).
The selected researcher will show a strong commitment in developing industrial partnerships and in setting up European and national research projects. He will also participate to consultant and expert activities in geotechnics.
Growth of slip surfaces (life is dangerous)
Alexander M. Puzrin, ETH Zurich, Switzerland
Growing slip surfaces are commonly encountered in the mechanisms of many natural geo-hazards, such as earthquakes, landslides, snow avalanches, tsunamis, etc.. The talk will explore the basic mechanics of progressive and catastrophic slip surface growth in a slope using recent advances in experimental, analytical and numerical approaches. Importance of the proper understanding of this phenomenon will be illustrated via the following three novel applications: (i) defining influence zones for terrestrial landslides, (ii) relating geomorphology of submarine landslides to their tsunami generating potential, and (iii) exploring plausibility of a delayed release for earthquake-triggered snow avalanches. In the process, it will be demonstrated how the slip surface growth can negatively affect life of an ordinary citizen.
Alexander M. Puzrin is Professor and Chair of Geotechnical Engineering at the ETH Zurich, Switzerland. He is engaged in the constitutive modeling of geomaterials and the analysis of progressive and catastrophic failure in soils, with applications to onshore and offshore slope stability problems. His other interests are in development of novel sensor technologies for geotechnical monitoring and in assessment and mitigation of geotechnical eco-hazards. Professor Puzrin has been involved as an expert and consultant in large-scale onshore and offshore geotechnical projects in the UK, the US, Switzerland, Mexico, Azerbaijan, Russia, and Israel. His research papers received multiple awards from the UK Institution of Civil Engineers (ICE). He served as the Editor of Géotechnique in 2012–2015.
Open Geomechanics — a peer reviewed, non-profit, open-access journal in geomechanics run by geomechanics researchers — is open and inviting publications.
High quality research submissions (in any geomechanics related topics such as analytical, numerical or experimental studies) or case studies, negative results, as well reproducibility studies are welcome.
If you believe that the large publishing houses are exploiting their positions of power, and believe in free and open communication of scientific results, please support this young journal in its early days and submit your next paper to us.

We have a vacancy for a 3 years PhD Fellowship at Department of Geoscience and Petroleum (IGP), NTNU. The work will be a part of the project: Improved prediction of stress and pore-pressure changes in the overburden for infill drilling at SINTEF’s Department of Petroleum, that is supported by the industry and the Research Council. The main objective of this project is to provide calibrated rock-mechanical and rock-physical models for overburden rocks for prediction of stress- and pore-pressure changes in the overburden of a depleting reservoir.

Predicting foundation response for offshore wind turbines Supervised by Britta Bienen, Conleth O’Loughlin
The aim of this research is to predict the installation and in service response of suction buckets supporting offshore wind turbines. This foundation concept is now being adopted in offshore wind farm designs. Following self-weight penetration into the seabed, the bucket is installed by pumping water out of the bucket, which creates a pressure differential across the lid and drives further penetration. In service, the foundation needs to resist the cyclic loading imposed on the turbine from the ocean environment. The mechanisms of suction installation (in layered soils in particular) and the effects of the installation process on the soil state are poorly understood. The evolution of foundation stiffness and displacement underpin the design. The research will be predominantly experimental, utilising recently developed purposedesigned experimental facilities. The project is a collaboration with Lloyd’s Register EMA and Melbourne University.
