Effectiveness of Geogrid and Geotextiles in Embankment Reinforcement
The Colorado Department of Highways constructed an embankment on a weak foundation on I-76 near Tennyson Street in Denver. In order to strengthen the embankment, a layer of Tensar SS-2, a polypropylene geogrid was placed between the foundation and the embankment prior to embankment construction. The foundation was instrumented with inclinometers, settlement transducers, and piezometers to measure the vertical and horizontal movements and pore water pressures. A study was undertaken to investigate the effectiveness of using Tensar SS-2 geogrid by comparing the settlements resulting when using Tensar SS-2 geogrid, Trevira 1127 nonwoven geotextile, a steel reinforcement and using no tensile reinforcement. Because it was not practical to construct multiple embankments, the study also used a finite element analysis. The finite element analysis results indicated that the use of Tensar SS-2 geogrid reinforcement has little effect in reducing the settlement of the embankment, nor did the other tensile reinforcements. This is primarily because the deformation of the embankment is predominantly in the vertical direction.
