Résumé / Abstract
The Inter PACIFICproject was aimed at assessing thereliability, resolution and variability of geophysical methods inestimating the shear-wavevelocity profile forseismic ground response analyses.Three different subsoil conditions, which can bebroadly defined assoft-soil, stiff-soil, and hard-rock, were investigated. Ateachsite, several participants performed and interpreted invasivemeasurements of shear wavevelocity(Vs) and compression wavevelocity(Vp) in the sameboreholes. Additionally,participants in the project analysedacommonsurface-wavedatasetusingtheirpreferredstrategies for processing and inversion to obtain Vs profiles. The most significant difference between the invasive borehole methods and non-invasive surface wave methods is related to resolution of thinlayers and abrupt contrasts, whichisinherently better for invasive methods
