Abstract: This study has examined the effect of vertical insertions or skirts on bearing capacity of bucket foundations or skirted footings on c-F soils. The parameters included thickness and depth of vertical insertions or skirts and the shape of footings. The pressuresettlement curves showed that thickness and depth of vertical insertions improves bearing capacity and in some cases the improvement is up to eight times. The shape of the footings also has effect on bearing capacity of c-F soils. The improvement in bearing capacity of square shaped skirted footings were found to be higher than the circular and rectangular shaped footings with vertical insertions
