Experimental Studies on Bearing Capacity of Inclined Skirted Footings on Sand

Abstract

This work discusses the suitability of inclined internal skirts along with outer vertical
insertions or skirts on bearing capacity of skirted footings on sand. The parameters includes
thickness and depth of vertical insertions as well as spacing of inclined internal skirts. The
scaled model footings made up of mild steel were considered for this research work. Square
and rectangle are the two shapes adopted. The size was designed in such a way that the
lateral confinement effect does not affect the test results. The foundation soil was in dry
condition. The readings of the applied load measurements were taken using a pressure cell
between the jack and the model footing and settlement was measured using the dial gauges
placed on the footing. The pressure-settlement curves showed that increase in thickness and
reduction in spacing increased bearing capacity.
