Title: GEOTEXTILE REINFORCED WRAP AROUND FACED WALL, PRAPOUTEL, FRANCE
Abstract: This case history describes the design and performance of a geotextile reinforced structure at the ski resort of Prapoutel-Les-?ep Laux, France. The aim was to widen a road passing along an existing embankment, to improve accessibility to several buildings and extend a car park. Geotextile was used rather than reinforced concrete, mainly to reduce costs. The design principle used was to assume a uniform active earth pressure over the whole height of the embankment. Conservatively, the calculation treated the embankment as a vertical wall. The selected geotextile was Stabilenka 200, a woven polyester product, with a tensile strength of 200kN/m and a strain at failure of 8% in the roll direction. The geotextile reinforcement lengths were 5m in the upper layers and 4m in the lower layers. The structure has remained very stable, ten years after its completion. It is remarkable for its age and height, and because it shows the possibility of using soils of poor characteristics with a generous safety margin, as is shown by the discrepancy between the characteristics assumed by the design and those actually measured on site.
