| چکیده | ||
| The present paper discusses the performance of clay bed reinforced with ordinary stone columns and geotextile encase stone columns using PLAXIS-3D. A surface ring footing having external diameter 200 mm and internal diameter 80 mm was used in the numerical modelling. In addition, vertical concentric loading was applied in the surface ring footing to produce its pressure-settlement behaviour. Moreover, a parametric study was carried out by varying the number (0, 4, 5 and 9), length (200 mm, 300 mm and 400 mm), diameter (32 mm and 50 mm) and geotextile encasement length (150 mm and 300 mm) of stone columns. From the numerical modelling it was observed that the inclusion of ordinary stone column in clay bed improved its load-carrying capacity significantly, i.e., up to 3 times, and to increase it even further, geotextile encasement is very useful. | ||
