This paper includes analysis of the performance of micropile systems under seismic loading. It presents results of both centrifuge model testing and three-dimensional finite element modelling carried out within the FOREVER research programme. The experimental and numerical results were analysed to study the effect of the main controlling parameters of the micropile-soil-structure systemsuch as the kinematic interaction, the group effect, the influence of micropile inclination, and performance assessment of micropile systems in liquefiable soils. Analysis shows that micropile systems offer effective engineering solutions for construction in seismic areas. Cette etude est constituee d'analyses de performances pour des systemes a micropiles soumis a des charges sismiques. Elle presente les resultats d'essais sur modele centrifuge ainsi que les resultats d'une modelisation en trois dimensions d'elements finis, le tout effectue dans lecadre du programme de recherche FOREVER. Nous avons analyse les resultats ex...
