ABSTRACT

The concept of the Limited Life Geotextile refers to the ability of the geotextile in providing additional stability to an embankment erected on soft ground until the foundation soil achieves the desired shear strength over time. In this paper an analytical method is used to investigate the short term and long-term stability of basal reinforced embankment erected on soft soil. The amount of Limited Life Geotextiles(LLGs) required to achieve a specific Factor of Safety on varying Foundation depth (D) and Embankment Height (He) (D/He ratio) as well as slope angle is investigated.

Keywords: Limited Life Geotextiles, free drain embankment, soft soil, reinforcement, Factor of Safety, Time Factor.
