Study of Prestressed Geotextile Reinforced Sand Supporting an Embedded Square Footing
The use of geosynthetics for the improvement of sandy soil is widely acknowledged. However, the effect of using geosynthetics is negligible for the small settlement of foundation resting over it. Therefore, prestressing the geotextile has a beneficial effect on the performance of the foundation even for the small settlement. In this study, the behavior of the square footing resting on the prestressed geotextile-reinforced sand is carried out through both laboratory model test and numerical analysis. The experimental study is performed using 100 mm × 100 mm (B × B) square footing embedded at a depth of 50 mm, resting on unreinforced sand and sand reinforced with both geotextile and prestressed geotextile. It is found that placing the geotextile at 0.2B depth below the footing gives the maximum improvement. The improvement of the study is reported in terms of bearing capacity ratio and settlement reduction ratio. Prestressing of the geotextile shows 73% reduction in the settlement and 261% increment in the bearing capacity in comparison to footing resting on unreinforced sand. The results of the numerical analysis using Plaxis 3D is found to be in good agreement with the experimental study.
