Embankment Reinforcement The use of geosynthetics to reinforce soils has enabled this technique to be adopted for a wide variety of applications, for example, reinforced soil walls, reinforced soil slopes, and reinforced embankments constructed over soft or unstable foundation soils.
The purpose of the geosynthetic reinforcement is to maintain equilibrium until consolidation can occur in the soft foundation soil. The foundation soil strengthens with time during consolidation and finally supports the embankment loading without need for the reinforcement. Reinforcement of an embankment on soft soil reduces construction material quantities, reduces land acquisition and reduces construction time. The incorporation of Basetex® high strength knitted geosynthetic reinforcement layer will intercept and interrupt the localised shear deformations which can occur in unreinforced soil. The high strength, low elongation, Basetex® reinforcing membrane will limit the load transfer onto the soft base layer. In some situations, the most economical final design may be some combination of a traditional foundation treatment alternative together with geosynthetic reinforcement. |
