Özet

A validated and calibrated finite element model has been generated using the results of the full-scale loading tests performed in the field. The affects of the footing size, initial stress state and stress history of sand layer, the thickness of upper sand layer and the undrained shear strength of lower clay layer on the bearing capacity and settlement behaviours of square footings on layered soils have been investigated by performing a series of three-dimensional finite element analyses. The bearing capacity values obtained from finite element analyses have been compared to the bearing capacity values calculated by punching shear method. Also, the variation of Ks coefficient depending on the H/B ratio and ƛs has been investigated.
