Geotechnical characterisation of sites is an important phase in the design of civil and infrastructure projects. It involves defining the geotechnical model of the subsoil, which is necessary for safety analyses and optimising the use of economic resources. In accordance with NTC 2018 (Chapter 6), characterisation is carried out through geognostic site investigations and laboratory tests to identify the physical and mechanical properties of the present soils and rocks in a significant volume.
Eucentre boasts internationally renowned expertise and experience in seismic geotechnical engineering applications. This includes evaluating local amplification effects and soil instability, particularly liquefaction, subsidence and lateral expansion in soils, while taking into account the spatial variability of subsoil properties. Eucentre also plans investigation campaigns for the geotechnical-seismic characterisation of sites, performing non-invasive geophysical tests, and evaluates the stability of natural and artificial slopes under seismic excitation. Eucentre is also able to perform advanced dynamic analyses, modelling the effects of soil-structure interaction. This approach is necessary in order to adequately assess the seismic response of on-shore, near-shore and off-shore facilities.
Eucentre’s Mobile LAB is equipped all the necessary tools for non-invasive seismic geophysical MASW, ReMi and H/V surveys. These surveys are aimed at geotechnical and seismic-stratigraphic characterisation of construction sites, and involve the joint measurement of S-wave velocity profiles and small deformation damping. Eucentre personnel are trained to carry out these investigations under ordinary conditions, as well as expeditious post-seismic surveys for sites of strategic interest.
