  abstract = {{T}his paper deals with the contribution of the ambient vibration horizontal-to-vertical spectral ratio ({HVSR}) method in soil engineering studies, particularly in backfill compactness assessment. {T}he study is based on 60 ambient vibration recordings performed in 2015 at the container terminal of {A}lgiers harbor, subjected a year before to a geotechnical study based on 23 boreholes and 13 cone penetration tests ({CPT}) for backfill improvement. {T}o highlight the contribution of the {HVSR} method, the results of the geotechnical and {HVSR} studies are first analyzed separately and then in combination. {T}he {HVSR} method provides a compactness zonation map based on peak amplitude variation. {B}oth methods define the same pattern: a southern section where the backfill is more compact, and a northern section where the backfill is less compact. {T}his shows that the {HVSR} peak amplitudes are sensitive to compactness variations, which may be sufficient for qualitative zonation. {I}n addition, with the combination of the two methods, rough estimations of shear-wave velocity and thickness of the backfill can be retrieved. {T}his study shows that the {HVSR} method can be a very useful investigative tool in soil engineering studies. {W}hen the {HVSR} method is deployed before any conventional technique, a geotechnical investigation campaign can be significantly optimized. {M}oreover the combined interpretation brings complementary quantitative soil information.},
