BEHAVIOUR OF PRESTRESSED GEOTEXTILE-REINFORCED FINE SAND BED SUPPORTING AN EMBEDDED SQUARE FOOTING

Abstract

This paper presents the results of laboratory model tests carried out on embedded square footing
supported on geotextile reinforced sand bed. The effect of reinforcement with geotextile were studies through a
series of laboratory model tests with different size of geotextile and depth of placement below footing. The
effects of prestressing the geotextile on the strength improvement and settlement reduction of a reinforced sand
bed are also being investigated. The model steel tank of size 120 cm x 50 cm x 50 cm and square footing of 10
cm are used. The study also highlights the effect of size of geotextile and placement of geotextile below footing
on load-settlement characteristics.
