Experimental Investigation of Square Footing Resting on Sand over Gypseous Soils

A field investigation of vertical footing response on sand

Study of bearing capacity of strip footing resting on reinforced sand

This research was performed to investigate the behavior of strip footing on geosynthetic reinforced sandy soil and to study the effect of different parameters contributing to their performance using laboratory model tests. The parameters investigated in the study included top layer spacing (u), width of reinforcement (b), vertical spacing between layers (s) and number of reinforcement layers (N...

Experimental and Numerical Study of Tension Bearing Capacity of Circular Skirted Foundations Resting on Sand Bed

Skirted foundations are an appropriate alternative to deep foundations in onshore and offshore structures, which have the ability to withstand uplift loads, are also easy to be installed. The tensile performance of skirted foundations on sand was studied by physical and numerical modeling. Laboratory tests were carried out on small-scale foundation models with peripheral skirts. Numerical model...

Intrusion of Geomesh in Gypseous Soil Under Single Footing

Methods to improve bearing capacity of footing resting of collapsing soil can, in fact, take two approaches, improving soil strength properties and intrusion of reinforcing sorces into soil. The footing is modeled by a square steel plate 0.1 by 0.1 m. The footing is loaded as to have a stress of 40 kPa and settlement is receded in dry and in soaking conditions. Two depths of the geo-mesh reinfo...

Bearing capacity of shell strip footing on reinforced sand

In this paper, the ultimate load capacities of shell foundations on unreinforced and reinforced sand were determined by laboratory model tests. A series of loading tests were carried out on model shell footing with and without single layer of reinforcement. The tests were done for shell foundation at different shell embedment depth and subgrade density. The results were compared with those for ...
