Performance of Geosynthetic-Reinforced Soil Structures at Limit Equilibrium State Available to Purchase

Potential failure mechanisms representing various limit equilibrium states of geosynthetic-reinforced soil walls/slopes are employed to study the behavior of reinforced soil walls/slopes. Parametric analyses were conducted to investigate the effects of varying the values of pore water pressure, soil strength, geosynthetic strength, soil-geosynthetic interaction coefficients, vertical spacing of geosynthetic, surcharge load, facing slope, and backslope. In the analyses, geosynthetic-reinforced soil walls/slopes are assumed to have competent foundations. Seepage forces and other dynamic forces such as earthquake forces have not been taken into account. Similarly, the stabilizing effects of facing rigidity and strength are neglected. The results are presented in a nondimensional graphical form. Methods of optimizing the design of geosynthetic-reinforced soil structures are suggested.
