Load settlement behaviour of granular piles

Abstract

In this thesis an examination is made of the vibro-replacement technique for the stabilisation of cohesive soils. Improvement is achieved by the formation of stiffer columns of granular material within the soil deposit using a large cylindrical vibrator referred to as a vibroflot. Granular piles (also termed stone columns) are used either singly or in small groups to supoort isolated footings or large numbers are installed in a regular array to support widespread loads. Each of these modes of application are investigated.
