Caractériser et prévenir la liquéfaction des sols sous les ouvrages : le projet ISOLATE

Abstract : The ISOLATE project aims at better characterizing the liquefaction of soils under seismic excitations in the lab and on site as well as limiting the damages to structures and lifelines. It is organized through five main topics: 1/ characterization at the scale of the material, 2/ characterization at the scale of the subgrade and assessment of scale effects, 3/ analysis of the effects of liquefaction on structures, 4/ risk reduction and assessment of an innovative mitigation method, 5/ recommendations for practitioners and publicizing the results. The involvement of renowned academic institutions in the fields of geotechnics, seismic risk, experimental, physical and numerical modelling (CEA, CS, ENPC, IFSTTAR) underlies the relevance of the proposed actions; that of major industrial stakeholders (EDF, SB) guarantees that the scientific and technical outcomes of this project will benefit to the economical field.
