In the present paper, interference effects on bearing capacity of two and three closely spaced strip footings resting granular bed overlying clay are being studied. A simple analytical model is proposed to predict load-carrying factor an interfered footing, when adjacent optimally placed surface a Granular Bed (GB) both simultaneously loaded. punching shear failure mechanism envisaged in model....

An experimental study of the effect of silt and influence of cell confinement on the bearing capacity of circular footings on silty sand was carried out. Laboratory experiments on clean sand and sand containing silt up to 25 % were performed. Cells with different heights and diameters were used to confine the silty sand. The effect of proportion of silt in sand, cell diameter, cell height and t...

In this paper, an experimental and numerical study was adopted to investigate the effect geogrid soil reinforcement prestressing on the pressure settlement relation of sand bed supporting a strip foundation. The studied parameters include foundation depth and pre-stress ratio for the cases of one and two pre-stressed reinforcement layers. The study reflected that pre-stressing of soil reinforce...

This paper presents the bearing capacity determination of strip footing placed on sand underlain by clay and subjected to inclined loading. The equation is derived within framework limit equilibrium following projected area approach. inclinations load spread were selected performing an additional finite element analysis. A parametric study was conducted highlight effect various input parameters...

As a result of the importance foundation in engineering construction, it is important to investigate bearing capacity construction soils, this study therefore investigated soils Ayedaade Local Government Area, southwest Nigeria. To achieve aim study, soil samples were collected from selected 20 sites area. Using standard procedures, preliminary and geotechnical tests such as natural moisture co...

There is a growing interest world-wide in the development of a rational reliability-based geotechnical design code. The reason for this interest is a least two-fold; first of all, geotechnical engineers face uncertainties which are commonly significantly larger than those faced in other fields of engineering and so there is a need to properly characterize and deal with this uncertainty. Secondl...
