Abstract
The use of stone column (called granular piles) has proved to be an economical and technically viable ground improvement technique for construction on soft soils and has been successfully applied for the foundation structure like oil storage tanks, earth embankments, raft foundation etc. When the stone columns are installed in extremely soft soils, the lateral confinement offered by the surrounding soil may not be adequate to form the stone column. In such soil, encasing the stone column with a geotextile can induce required lateral confinement. Considering the cost aspect of stone columns, the major portion of the cost owes to the cost of stone. If replacing a portion of stone by some other cheaper material, without affecting the performance, can reduce the total cost In the present work experimental studies are carried out to evaluate the behavior of stone column encased with geotextile, in which stone is replaced by cheaper quarry dust The effect of geotextile is also studied. It is revealed from the studies that a portion of stone can be replaced by cheaper quarry dust without with out affecting the performance of the column.
