EMBANKMENT WITH VERTICAL WALL REINFORCED WITH SYNTHETIC NON-WOVEN MATERIAL

REMBLAI A TALUS VERTICAL ARME AVEC UN TEXTILE SYNTHETIQUE

An experimental embankment consisting of weathered chalk and wet clay, 4m high and 20m long, was built along the A15 motorway. It was reinforced with sheets of bidim inserted every 50cm. The aim of the experiment was to investigate the stability, adaptation and deformability conditions. Details are given of the materials used: for the subgrade (a 1M- layer, hardly compressible, situated towards the surface of the embankment, a non-compressible 3m-layer of peat and silty gravel); for the embankment (mixture of weathered chalk, clay and flint); for the reinforcement: bidim (synthetic polyester non-woven material). It is assumed that 2/3 of the internal friction of the soil ensures the adhesion of the bidim to the soil. The deformability of bidim was determined in deformation tests up to failure point, by means of a pressiometer. Details are given of the results of these tests, the design and construction of the embankment (protection of the vertical wall, preparation of the reinforcement, equipment used for measurements of profiles), horizontal displacements observed on small control plates and measured, settlement of the subgrade, strain gauges, etc. The overall behaviour of the embankment was judged to be satisfactory. /TRRL/
