STAGE - CARACTERISATION DES MATERIAUX EXCAVES AU TUNNELIER AVEC L’OBJECTIF DE REEMPLOI BAS CARBONE EN TERRASSEMENT
Core
Develop low-carbon treatment protocols and characterization methods to enable the reuse of excavated tunneling materials (marins) in earthworks, reducing environmental impact and landfill use.
Role type
Research stage (geotechnical engineering and material science)
Builds
Reliable protocols for characterization, treatment, and control of excavated materials for reuse in embankments and earthworks.
Domain
Geotechnical engineering, circular economy, low-carbon construction materials
Required skills
geotechnical characterization, soil mechanics, rock mechanics, bibliographic analysis, environmental assessment, experimental data analysis, technical recommendation formulation
Preferred skills
advanced soil/rock behavior modeling, knowledge of low-carbon binders (geopolymers, activated clays, ternary binders), experience with industrial by-products
Technologies
geotechnical testing equipment, numerical simulation tools, low-carbon binders (geopolymers, activated clays, ternary binders), industrial by-products
Responsibilities
Conduct literature review on tunneling excavation methods and material characterization; evaluate alternative low-carbon treatment solutions (physical adaptations, binders, bio-cementation); analyze effects on compaction, bearing capacity, and durability; perform multicriteria techno-environmental analysis and propose reuse recommendations.
Seniority
Intern (final year engineering student)
