LG4 – Geotechnical, Geoenvironmental, Geomechanical, and Geophysical Laboratory
The activities of the Geotechnical, Geoenvironmental, Geomechanical, and Geophysical Laboratory (LG4) are focused on characterizing and modelling the hydrogeomechanical and hydrogeochemical behaviour of unconsolidated deposits of geological and anthropogenic origin as they interact with the human environment.
Research
Overview of LG4 research projects:
- Enhancing the representativeness of geotechnical and geoenvironmental characterizations;
- Developing a geovalorization approach pertaining to contaminated soils and residual materials;
- Improving the safety of geotechnical structures and the prediction of natural geological hazards (e.g.: landslides, liquefaction).
Areas of expertise:
- Geotechnical engineering, soil mechanics, rock mechanics
- Hydrology, hydrogeology, groundwater
- Remote sensing
- Mining construction, tunnelling, underground space engineering and rock excavation
- Geohazard monitoring and mitigation (landslides, rockslides, subsidence, rockfalls)
- Rock and soil mass characterization and laboratory testing
- Environmental characterization and representative sampling.
Services offered
The experts at LG4 offer various collaboration opportunities through research partnerships or consulting mandates. To learn more or explore potential avenues for collaboration, we invite you to contact the professor with the relevant expertise directly, or the laboratory director, who can guide you to the appropriate resources. The laboratory also provides testing services. Below is a list of available equipment and the tests conducted in the lab.
Laboratory Equipment and Testing
Rock Testing:
- Block coring and specimen preparation
- Uniaxial compression (capacity of 2000 and 4000 kN)
- Elastic modulus
