Géotechnique pour le Développement Durable dans le Contexte du Changement Climatique
Les nations du monde entier sont confrontées à un défi sans précédent : garantir une énergie sécurisée tout en limitant le réchauffement climatique. Parallèlement, le réchauffement climatique aggrave les conditions météorologiques extrêmes, augmentant ainsi la fréquence des géorisques tels que les effondrements, les glissements de terrain et les tremblements de terre. Il est ainsi essentiel de contribuer au développement des énergies vertes tout en protégeant les infrastructures contre ces événements potentiellement catastrophiques.
Les ingénieurs géotechniciens jouent un rôle central dans la résolution de ces problèmes en fournissant des solutions novatrices pour faire face au changement climatique et en proposant de construire des infrastructures durables. Mes travaux de recherche en géomécanique et en intéraction sol-structure sont à l'interface entre le domaine de l'énergie et celui de la conception d'infrastructures durables. Mes travaux ont pour but de développer des solutions géotechniques dans le contexte du changement climatique et se divisent en deux axes de recherche principaux:
1 | La conception et l'optimisation des fondations et structures de support des éoliennes offshore
J'ai plus de 10 ans d'expérience de recherche sur l'amélioration des méthodes de calculs et la compréhension du comportement des fondations des éoliennes offshore soumises à diverses conditions de charge :
- chargement cyclique à grand nombre de cycles (modèle HARM)
- charge ultime et chargement monotonique (modèle PISA)
- excitations sismiques (en particulier, le comportement de la pièce de transition)
- Systèmes d'ancrage pour les éoliennes flottantes
- Transfert de connaissances pour l'optimisation des fondations éoliennes terrestres afin de réduire les émissions de carbone et les coûts
2 | Système d'alerte précoce pour les effondrements de sol de type doline ou fontis
Je suis la responsable académique du projet SINEW, un projet de recherche en cours visant à développer un système d'alerte précoce pour les mouvements du sol, et basé sur une combinaison de détection par fibre optique et de surveillance par satellite. Ce projet s'effectue en collaboration avec l'Université de Pretoria (Afrique du Sud), l'Université Federico II (Naples, Italie), l'Université de Cambridge (Royaume-Uni) et l'Université de Manchester (Royaume-Uni).
Biographie
Dr Christelle Abadie est l'une des chargées de recherche au sein du groupe Centrifugeuses Géotechniques de l'Université Gustave Eiffel, sur le Campus de Nantes (Bouguenais). Elle est titulaire d'un diplôme d'ingénieur des Grandes Ecoles de l'ENSTA ParisTech et d'un doctorat en génie civil de l'Université d'Oxford. Au cours de son doctorat, elle a étudié la réponse des fondations monopieux à des chargements latéraux cycliques à long terme (modèle HARM), suivi d'un post-doctorat à l'Université d'Oxford, sur le projet PISA2 (Pile Soil Analysis). Elle a ensuite poursuivi ses recherches en tant que professeure adjointe en génie civil à l'Université de Cambridge, où elle était membre de Fitzwilliam College. Elle est actuellement co-secrétaire générale de la conférence ISFOG 2025 (International Symposium for Frontiers in Geotechnics) qui se tiendra à Nantes en juin 2025.
Geotechnics for Sustainable Development in the Context of Climate Change
Countries across the world are grappling with the unprecedented twin challenge of providing secure energy while curbing global heating to avoid the worst eects of the current climate crisis. In parallel, on-going global warming enhances local extreme weather conditions, which in turn increases the frequency of geohazards, such as sinkholes, landslides or earthquakes. Contributing to the development of green energy sources while protecting infrastructure against the occurrence of this potentially catastrophic geohazardous events is becoming increasingly important for the built environment.
The geotechnical engineers and researchers play a central role in addressing these issues and providing novel and innovative solutions to combat and adapt to climate change whilst constructing sustainable infrastructure for the future. My research in geomechanics and soil-structure interaction is at the interface between energy and sustainable infrastructure, with the aim of developing geotechnical solutions in the context of climate change.
I focus principally on two main axes of research:
1 | The design and optimisation of foundations and support structures for wind energy applications
I have over 10 years research experience working on improving design methods and further understanding the behaviour of foundations for offshore wid turbines subjected to a range of loading conditions:
- Long-term cyclic loading (principally the HARM model)
- Monotonic ultimate limit loads (PISA method)
- Seismic excitations (in particular, the behaviour of the transition piece)
- Anchors for floating offshore wind turbines
- Knowledge transfer for optimisation of onshore wind foundations for carbon emission and cost reductions
2 | Modelling and monitoring of ground movements for climate-change induced geo-hazards
I am the academic lead for the SINEW project, an on-going research project that aimed at developing an early-warning system for ground movement based on combined fibre optic sensing and satellite monitoring. This project is in collboration with the University of Pretoria (South Africa°, the University Federico II (Naples, Italy), the University of Cambridge (UK) and the University of Manchester (UK).
Short Biography
Dr. Christelle Abadie is a research fellow in sustainable development and is part of the Geotechnical Centrifuge group at the Université Gustave Eiffel, on the Nantes Campus (Bouguenais). She holds an Engineering degree from the French “Grandes Ecoles” ENSTA ParisTech, and a D.Phil from the University of Oxford. During her PhD, she studied the response of monopile foundations to long-term cyclic lateral loading (HARM model), and continued studying offshore wind monopiles through a PDRA at Oxford, working on the PISA2 project (Pile Soil Analysis). She then continued her reseqrch as an assistant professor in civil engineering at the University of Cambridge, where she was a fellow of Fitzwilliam College. She currently is the co-general secretary of the ISFOG 2025 conference (International Symposium for Frontiers in Geotechnics) to be held in Nantes in June 2025.
