MODELLING OF REINFORCED SOIL

Abstract

Geosynthetics are being used increasingly to improve soil properties and to obtain better performance from soft or weak foundation sites. It is well-known that the overall stability is improved and that the movement of the structures founded on the reinforced soil reduces because of the mobilization of tensile forces in geosynthetics. This force is well quantified in the analysis of stability of structures constructed with reinforced soil. However, studies on modelling aspects are not many. In this paper, models are considered to quantify the effect of tensile force. Solutions for an embankment (strip) type of load are presented.
