Christophe Chevalier
Chercheur HDR en interactions eau-sol-structure Directeur du département GERS
Christophe Chevalier is a senior, HDR, researcher and director of the GERS department (Geotechnical Engineering, Environment, Natural Hazard and Earth Sciences - approx. 130 people). Since 2007, his research activities have focused on the vulnerability of soils and structures (dikes and bridges) to the risks of erosion and scour. He has been in charge of several national research projects including ANR SSHEAR (7 public and private partners) on the issue of scouring between 2015 and 2019. He was also the scientific leader for Univ. Eiffel (formerly Ifsttar) in the CPER-FEDER PACA 2017-2020 Digue2020 project on a research platform in marine environment to study the impact of the sea on dikes. He is the French representative to the "scour & erosion" technical committee of the International Society of Soil Mechanics. He took part in writing CFBR Technical guidance « Methods and technical solutions for levees reinforcement » and is coordinating a CFMS working group on the « monitoring of geotechnical structures » (guidance to be published in early 2025). He wrote more than 28 WoS referenced articles (h-index of 11) and numerous communications. He has co-organized national and international conferences like the 2012 International Conference on Scour and Erosion.

Journée publique de restitution du proejt ANR SSHEAR sur les affouilllements ayant réuni près de 70 personnes.
Livret des résumés et présentations disponibles en ligne : https://sshear.ifsttar.fr/toute-lactualite/actualites-details/news/seminaire-de-cloture-du-projet/
Les processus d’affouillement sont une cause importante de destruction des constructions (ouvrages d’art, ouvrages en terre et bâtiments) notamment lors des crues majeures mais leur prise en compte reste trop empirique. L’objet du projet SSHEAR est l’amélioration des connaissances sur les mécanismes d’affouillement et le développement d’outils novateurs d’observation et de modélisation aux échelles tant de maquettes expérimentales que d’ouvrages réels en vue de proposer des méthodes optimisées de diagnostic, d'alerte et de gestion. Le contexte du projet est d’un côté celui d’une expertise scientifique et technique quasi-inexistante actuellement sur la scène nationale et d’un autre celui d’une expertise internationale tournée vers des problématiques différentes de celles intéressant le territoire français. Le projet doit donc créer les conditions nécessaires à l’émergence de cette expertise nationale, au cours ou à la suite du projet. Pour avancer sur l’amélioration des connaissances et proposer des méthodes optimisées de diagnostic, d'alerte et de gestion, le projet propose ainsi une approche multi-échelle et pluridisciplinaire basée sur : - les processus physiques d’écoulement et d’érosion à proximité d’ouvrages (ponts, berges…) ; - trois expérimentations de laboratoire offrant une observation multi-échelle ; - une approche réellement novatrice de modélisation biphasique ; - les observations et les enregistrements de terrain ainsi que des développements de matériel.

La Région Paca compte plus de 2700 km de digues fluviales et maritimes et près de 250 gestionnaires. L'adaptation au changement climatique est un enjeu majeur : son littoral subira notamment l'élévation du niveau de la mer. Face à ce constat, le projet DIGUE 2020 a été réfléchi et élaboré par plusieurs partenaires : les laboratoires, Inrae, Cerema,Univ. Eiffel, ESPACE, et un syndicat mixte d’aménagement des digues, le SYMADREM. Ce projet consiste à mettre en place une plateforme de recherche scientifique sur les digues maritimes avec notamment la construction d'ouvrage en sol chaux soumis à des sollicitations réelles. Le module 3, piloté par l'Univ. Eiffel, a pour objectif d’aborder pour la première fois en France les questions de durabilité encore peu maitrisées sur une digue en sol-chaux en site maritime : effet du temps, enchainement des cycles saisonniers, action cyclique à très grand nombre de cycles de la mer, action des vagues, actions physico-chimiques. Après une étude complète sur matériaux modèles en laboratoire menée dans le cadre de la thèse de Margot De Baecque soutenue en décembre 2019, la réalisation de l'ouvrage, incluant la mise en oeuvre de certains dispositifs géophysiques à demeure s'est terminée en mai 2020. L'instrumentation géophysique (électrique et sismique) de l'ouvrage par le laboratoire GéoEND a été finalisé fin juillet 2020 avec l'acquisition de premiers résultats au cours du 2nd semestre 2020.
