520 | |a Abstract The present paper investigates the behaviour of circular shallow footings on soft clay soils with skirted and non-skirted sand piles. The main goal of this study is to evaluate the settlement and bearing capacity of a circular foundation, which is placed on a soft clay layer, based on a sandy soil layer. Different piles with varying length to clay layer thickness ratios ranging from 0.25 to 1 were modelled experimentally, as well as numerically, both with and without skirt. The effects of using a steel skirt and the length to clay layer thickness ratio of the piles, compared to the case in which the footing is placed on a pile without any skirt, and in the case of a shallow foundation without piles, were also investigated in this study. A model generated by finite element software was also used for numerical analysis. The results indicate that the use of skirted piles can affect the load–settlement curves and increase the bearing capacity. By increasing the ratio of pile length to clay thickness, the bearing capacity of the shallow foundation will be increased and the corresponding settlement will be decreased. Therefore, the bearing capacity failure mechanism of a footing resting on soft clay can be modified from the punching failure to the general shear failure at the tip of the confined replaced sand column. Load–settlement diagrams and bearing capacity obtained by numerical results are in accordance with the results derived from experimental observations. | ||

The main goal of this study is to evaluate the settlement and bearing capacity of a circular foundation, which is placed on a soft clay layer, based on a sandy soil layer. Different piles with varying length to clay layer thickness ratios ranging from 0.25 to 1 were modelled experimentally, as well as numerically, both with and without skirt. The effects of using a steel skirt and the length to clay layer thickness ratio of the piles, compared to the case in which the footing is placed on a pile without any skirt, and in the case of a shallow foundation without piles, were also investigated in this study. A model generated by finite element software was also used for numerical analysis. The results indicate that the use of skirted piles can affect the load–settlement curves and increase the bearing capacity. By increasing the ratio of pile length to clay thickness, the bearing capacity of the shallow foundation will be increased and the corresponding settlement will be decreased. Therefore, the bearing capacity failure mechanism of a footing resting on soft clay can be modified from the punching failure to the general shear failure at the tip of the confined replaced sand column. Load–settlement diagrams and bearing capacity obtained by numerical results are in accordance with the results derived from experimental observations.

The main goal of this study is to evaluate the settlement and bearing capacity of a circular foundation, which is placed on a soft clay layer, based on a sandy soil layer. Different piles with varying length to clay layer thickness ratios ranging from 0.25 to 1 were modelled experimentally, as well as numerically, both with and without skirt. The effects of using a steel skirt and the length to clay layer thickness ratio of the piles, compared to the case in which the footing is placed on a pile without any skirt, and in the case of a shallow foundation without piles, were also investigated in this study. A model generated by finite element software was also used for numerical analysis. The results indicate that the use of skirted piles can affect the load–settlement curves and increase the bearing capacity. By increasing the ratio of pile length to clay thickness, the bearing capacity of the shallow foundation will be increased and the corresponding settlement will be decreased. Therefore, the bearing capacity failure mechanism of a footing resting on soft clay can be modified from the punching failure to the general shear failure at the tip of the confined replaced sand column. Load–settlement diagrams and bearing capacity obtained by numerical results are in accordance with the results derived from experimental observations.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Skirted pile</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bearing capacity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Circular footing</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Soft clay soil</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Experimental study</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Numerical analysis</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Boushehrian, A.

Experimental and Numerical Study of Bearing Capacity of Circular Footings on Layered Soils With and Without Skirted Sand Piles |
abstract |
Abstract The present paper investigates the behaviour of circular shallow footings on soft clay soils with skirted and non-skirted sand piles. The main goal of this study is to evaluate the settlement and bearing capacity of a circular foundation, which is placed on a soft clay layer, based on a sandy soil layer. Different piles with varying length to clay layer thickness ratios ranging from 0.25 to 1 were modelled experimentally, as well as numerically, both with and without skirt. The effects of using a steel skirt and the length to clay layer thickness ratio of the piles, compared to the case in which the footing is placed on a pile without any skirt, and in the case of a shallow foundation without piles, were also investigated in this study. A model generated by finite element software was also used for numerical analysis. The results indicate that the use of skirted piles can affect the load–settlement curves and increase the bearing capacity. By increasing the ratio of pile length to clay thickness, the bearing capacity of the shallow foundation will be increased and the corresponding settlement will be decreased. Therefore, the bearing capacity failure mechanism of a footing resting on soft clay can be modified from the punching failure to the general shear failure at the tip of the confined replaced sand column. Load–settlement diagrams and bearing capacity obtained by numerical results are in accordance with the results derived from experimental observations. |
