A full scale 7.5m high by 15m wide geogrid reinforced soil wall has been constructed of cohesive soil. Non-woven fabrics were used for the drainage of the soil. The purpose of the test wall was to evaluate the applicability using cohesive soil. Full scale field_performance during and after construction was monitored by incorporating extensive instrumentation including: deformation plates of the wall, pore water pressure meters and earth pressure cells in the backfill, extensometers, displacement rods and strain gauges on geotextiles.
This paper gives well documented results of the several measurements and reports on the applicability of a reinforced soil wall using cohesive soil.
