Paper Title :: A Parametric Investigation on the Bearing Capacity of Reinforced Granular Soil, Overlying Clay

Page Number :: 01-05
In the present study, an attempt has been made to comprehensively investigate the bearing capacity characteristics of shallow strip footing, placed on a geogrid reinforced granular soil and underlain by a soft clay deposit. A finite element limit analysis (FELA)approach has been used to obtain the upper bound value of the true collapse load. Investigation of several critical parameters, such as thickness of the sand layer, friction angle of the sand, and number of geogrid layers are investigated under a parametric framework and the results are presented in the form of charts. Based on the results obtained, the efficacy of installation of geogrids has been established and subsequently, their optimal spacing has been obtained. Present study would be highly beneficial to the practicing civil engineers while designing a shallow foundation over a granular soil, underlain by a weak clay soil layer.
