Abstract
Use of stone columns for ground improvement in clayey soil is a common practice. Due to the high cost and scarcity of stone in some areas, jhama (over burnt brickbats) are being used as an alternative to stones. It is intended in the present study to compare the load carrying capacity of stone columns with that of jhama columns through laboratory tests and to conclude whether the jhama columns can be an alternative to stone columns. Model tests were carried out on 50 mm diameter and 400 mm long columns embedded in soft clay in a tank of size 1 m × 1 m × 1 m. The load-settlement plots were studied to observe the difference in behaviour of a stone column and a jhama column in terms of bearing capacity and mode of failure. A numerical analysis using Plaxis-2D was also carried out to observe the load-settlement behavior of all the models. A good agreement of experimental and analytical results was observed.
