Long-term behaviour of a 13 m high reinforced steep soil slope. Paper presented at Euro Geo 1 Maastrict

Abstract

In the summer of 1993 a 13 m high reinforced soil slope was built in the City of Lillehammer as part of the new road system constructed in conncection with the 1994 winter olympic games. The reinforced soil slope with an inclination of 60 degrees and a vegetated front was selected as an alternative to a reinforced concrete wall. This proved to be a very cost effective solution. The reinforcement used was a woven polyester geotextile with a characteristic short time tensile strength of 150 kN/m. In-situ materials consisting of silty, gravelly sand were used as backfilling materials. An inclinometer channel and six thermistors wew installed in order to measure horizontal deformations and temperature variations in the structure respectively.
