Title

NUMERICAL ANALYSIS OF CIRCULAR SKIRTED FOUNDATION RESTING ON SAND

Abstract

Skirted foundation is the foundation which has vertical or inclined wall surrounding one or more sides of the soil mass below the footing. These walls (structural elements) are called as the skirts. It is nothing unusual but the normal footing except the presence of skirts hence, may vary as per their shapes-circular, rectangular, and square. These vertical skirts restricts the soil beneath and bring about a soil resistance on skirt side that helps it to resist sliding. The soil starts to behave as soil plug to transfer the loads from the super structure to the larger depths and thereby increasing its bearing capacity. The various factors affecting bearing capacity include the type of soil, water table properties. The enhancement in performance of these foundations usually rely upon footing shape, size, depth , structural and geometrical properties of skirt, roughness and material of skirt and the soil characteristics such as the index properties, interface conditions of the soil-skirt system. In the present work, the numerical analysis of circular skirted foundation resting on the sand is carried out using the finite element software Plaxis 2-D. The different parameters on which the study is based are the variable skirt depth (0.5D to 3D), variable foundation diameter(1m to 4 m) and their combined effect on the vertical load bearing capacity is being analyzed. On comparing their results using the Force v/s settlement curves, the study revealed that the load carrying capacity of the sand increased both with increase in depth of the skirt and diameter of the footing. The values of load carrying capacity considered in the analysis are corresponding to 40 mm settlement.

Key Words

Bearing capacity, Circular skirted foundation, sand, skirt depth.
