DESIGN OF GABION-GEOSYNTHETIC RETAINING WALLS ON THE TELLICO PLAINS TO ROBBINSVILLE HIGHWAY

During construction of the Tellico Plains to Robbinsville highway several mechanically stabilized earth (MSE) walls were built with hybrid wall system components, consisting of geogrid reinforcement and PVC coated gabion baskets. The selection of these materials was based primarily on the presence of a chemically active soil environment, availability of an economical fill source, aesthetic appearance, and overall cost. This paper summarizes the design procedures utilized to ensure wall stability along a mountainous highway alignment. It examines how the general MSE design guidelines presented in the project specifications can be augmented with currently accepted methods of analysis to provide a safe but economical wall design. Project and product-specific test results used in the engineering analysis of a 10m high MSE wall system that also functions as a toe buttress for a 30m high slope are presented.
