LG – LABORATORY OF GEOTECHNICS

LG allows the development of fundamental research on the stress-strain behaviour of soil from very small deformations to failure conditions under monotonic and cyclic loading; mechanical, hydraulic, and electrical characterization of geomaterials in saturated and unsaturated conditions; field tests such as quality control and dynamic load tests on piles and seismic tests for geophysical characterization.
