Combined loading capacity of skirted circular foundations in loose sand

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...

A comparison of the bearing capacity of flat and conical circular foundations on sand

T. Orr, Trinity College Dublin, Ireland The authors have presented an interesting paper concerning a fundamental problem for geotechnical engineers: the bearing capacity of circular foundations on sand. In this paper the authors have included an equation for the factor Na in the bearing capacity equation for circular foundations on the ground surface, which has been determined from the results ...

Capacity of grillage foundations under horizontal loading

A comparison of the combined load behaviour of spudcan and caisson foundations on soft normally consolidated clay

Experimental data from loading tests of model circular footings on soft normally consolidated clay are presented. The experiments were carried out on a drum centrifuge at a radial acceleration level equivalent to 100 times Earth’s gravity, ensuring conditions of stress similitude between the model and the prototype scale. The aim of the experiments was to compare the undrained response of diffe...

Experimental Study on the Responses of Bucket Foundations in Calcareous Sand under Vertical Dynamic Loading

Experiments to determine the vertical static bearing capacity are carried out first in laboratory which is taken as a reference for choosing the amplitudes of vertical dynamic loading. Then a series of experiments are carried out to study the influences of factors, such as the scales of bucket, the amplitude and frequency of loading, the density of soils etc.. According to the experimental resu...
