ABSTRACT
The present study aims to generate generalized equations for the determination of ultimate load-bearing capacity (ULBC) of geogrid reinforced foundation (GRF) soil using the wraparound ends technique. Firstly, the ULBC of the reinforced soil is investigated by employing the two-dimensional FEM tool, and then a multiple linear regression (MLR) analysis is performed to obtain the generalized equations for the determination of the same. A series of solutions have been generated by performing a parametric study on the geometrical configuration of the wraparound ends configuration along with the geogrid’s axial elastic stiffness (EA). The results recommend that the generated equations are reliable as the coefficient of determination (R2 ) ranges nearly 1 for EA up to 2000 kN/m. However, beyond certain values of stiffness parameters, some qualitative intervention is needed to interpret the ULBC.
