Laboratory of Soil Mechanics

Our laboratory, our identity.

Message from Professor Lyesse Laloui

Professor Lyesse Laloui

I would like to welcome you to the Laboratory of Soil Mechanics. Beside the conventional geomechanical research activities, my research group gives priority to the protection of environment, landforms and structures from geo-hazards and industrial damage. Our experimental and modelling resources are mobilised to understand, investigate and predict the environmental impact of the new technologies such as nuclear waste disposal, and to provide tools for the up-to-date design of the geo-structures. In addition, in the context of the Chair “Gaz Naturel”, we focus our activities on the geo-engineering and the CO2 storage.Our scientific and technological developments are permanently transferred to education and industry

The Laboratory of Soil Mechanics (LMS) is one of the laboratories within the School of Architecture, Civil and Environmental Engineering of the Swiss Federal Institute of Technology, Lausanne (EPFL). Since its establishment, as the successor of Geotechnical Laboratory founded in 1935, the LMS has been contributing to fundamental and applied research activities, education, as well as civil engineering constructin works. The Soil Mechanics Laboratory gives priority to the protection from geo-hazards and industrial damage to the environment, landforms and structures. Our experimental and modelling ressources are mobilised to understand, describe and predict the environmental impact of the technologies of future days.

The LMS focuses its activities around three major fields:


The education delivered by the LMS includes the lectures and exercises delivered at the EPFL, and in other Swiss and foreign universities as well as in some universities of applied sciences. The major fields of education offered by the LMS are Soil Mechanics, Groundwater Flows, Foundation & Geotechnical Engineering, Safety & Reliability, for the Undergraduate Students and some specificically designed courses for the Post-graduate & Doctoral Students.

Research & Development

Research activities within the LMS deal, on the one hand, with theoritical and applied aspects in geotechnical engineering and, on the other hand, with the development of tools and computation methods for the analysis and/or design of geostructures and natural phenomena, aiming at the practical application of the obtained results.

Consulting Services

The consulting services offered by the LMS deal with the preparation and updating of national and international standards and codes, laboratory and in-situ geomechanical tests, monitoring of structures and construction sites, numerical modelling, and expert’s reports.
