ABSTRACT
The theme of this research is to study the effect of geosynthetic material on reinforcing foundation soil. First, numerical models of foundation soil layers are built to simulate published cases. The numerical approach is validated by the promising comparison with the loads and deformations both concerning the trends and the magnitudes as reported in literature. A numerical simulation set consisting of 218 simulations by varying the important design parameters including the thickness of base layer, https://www.w3.org/1998/Math/MathML"> C B R https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780429227196/8b5c0a5d-ddea-4c88-8eea-7152f7afb008/content/eq9502.tif" xmlns:xlink="https://www.w3.org/1999/xlink"/> of subbase layer, elastic stiffness of geosynthetic material, and the placing depth of geosynthetic material, is then conducted. The database of maximum surface settlement is regressed for the approximate equation between design parameters. The suitability of approximate equation is validated by a sound comparison with numerical simulation results. The settlement of geosynthetic reinforced foundation soil layers can be estimated from applying the approximate equation developed from this research.
