Résumé:
This numerical study aims to enhance the bearing capacity of shallow foundations built over
weak soils by investigating different soil types and geotextile reinforcement configurations
using PLAXIS 2D software. The research focuses on two main techniques: a simple
horizontal reinforcement layout and a full wraparound method, where geotextile fully
surrounds the soil including lateral and top sides, and is filled with soil from the inside and
additionally covered from the top. Several key parameters were analyzed, including the
embedment depth of the top geotextile layer (U), the width of the reinforcement (W), the
vertical spacing between layers (H), and the number of geotextile layers (N). The results
showed that the full wraparound configuration significantly outperformed the simple
horizontal reinforcement in terms of bearing capacity improvement. The study also identified
optimal ranges for the dimensionless parameters U/B, W/B, H/B, and N. These findings offer
practical insights into cost-effective and performance-optimized design strategies for
reinforced soil foundations.
