摘要

This study presented a numerical investigation of the bearing capacity of strip footings on sand reinforced with inclined wrap-around ends of geosynthetic layers using finite-element limit analysis. Unlike previous research that primarily focused on horizontally placed reinforcements, this work explored the performance and efficiency of geosynthetics with inclined wrap-around ends. A detailed parametric study was carried out to examine the influence of key factors, such as the inclination angle of the wrap-around ends, reinforcement width, and the depth of the first reinforcement layer, on the ultimate bearing capacity. The results indicated that the inclined wrap-around configuration significantly improved the load-bearing performance of shallow foundations by promoting more effective load transfer and enhancing soil confinement. The findings highlighted the potential of inclined wrap-around geosynthetic systems to provide optimized, economical, and efficient reinforcement solutions to improve the stability of foundations on sandy soils.
