Footing on double-faced wrap-around reinforced soil walls

The response of double-faced wrap-around reinforced soil retaining walls subjected to strip loading on the surface has been studied by conducting small-scale model laboratory tests. Model reinforced soil walls were constructed using Kalpi sand as backfill material and geotextiles as reinforcing elements. In the present study, two different multifilament geotextiles were used. Strip loading was applied at the centrally placed footing on the surface of the wrap-around reinforced soil walls. The influence of the number of reinforcing layers and overlap length on load deformation behaviour, ultimate bearing pressure and initial tangent modulus of the footings on double-faced reinforced soil walls was studied. The lateral deformations of wrap-around wall facing with settlement of the footing are also presented.
