A TEST FILL FOR GEOGRID REINFORCEMENT OF COHESIVE SOILS

A geogrid reinforced cohesive soil test embankment 12 metres high with 1:1 side slopes is under construction in the province of Alberta. Three different types of geogrids are being evaluated at the site, including tensar SR2, signode tnx-5001, and paragrid 50s. This paper outlines the geometric layout for the test fill and the design methods currently used for this type of reinforced slope. Instrumentation has been installed to monitor pore pressure responses and the deformations of both the in situ foundation soils and the compacted fill material. Through the analysis of the soil-geogrid interaction performance, a rational design approach will be developed for high geogrid reinforced slopes constructed with cohesive soils. For the covering abstract of the conference see IRRD 807201.
