Improvement of Bearing Capacity of Shallow Foundation Resting on Wraparound Geotextile Reinforced Soil
The scarcity of competent load-bearing strata for the foundation of the various structure has built pressure on geo-technicians to use the soil with poor strength employing numerous ground modification techniques. Reinforcing soil strata using geotextile material is a well-established, cost-effective, and proven methodology to improve the bearing capacity of the foundation. However, limited space in the periphery may hinder the placement of the reinforcing layers. Therefore, the potential application of the wrapping technique is evaluated in this study to ascertain the effectiveness of the reinforcement system. For the established aim, a parametric study is carried out using a numerical tool based on the finite element method, and the failure mechanisms of various configurations are studied, which showed that the ultimate load-bearing capacity can be increased up to 68% with the use of wraparound geotextile. Furthermore, an optimum overlapping length of the wrapping ends and vertical spacing between successive reinforcing layers are recommended as 0.6- and 0.3-times width of the footing, respectively.
