Settlement of embankment on reinforced granular fill - Soft soil system

A mechanical modeling approach has been adopted for settlement analysis of geosynthetic-reinforced granular fill - soft soil system subjected to embankment loading. The parametric studies bring out the effects of various factors such as load intensity, prestress in geosynthetic reinforcement, compressibility of granular fill, and consolidation of soft foundation soil. This approach can also be used to study the effect of several other factors like shear modulus of the granular fill, lateral stress ratio in the granular fill, and fill-geosynthetic interface characteristics. The results have been presented in nondimensional form which may be directly used in practical applications for the range of parameters studied. Prestressing the geosynthetic reinforcement has been found to reduce the differential settlements significantly.
