Researchers at the Transportation Technology Research, Inc. (TTCI) site in Pueblo, Colorado asked GeoStabilization International to provide a cost effective solution for a problematic railroad embankment at their research facility. A test embankment consisting of “Buckshot” clay imported from Mississippi had failed twice, fouling the line and causing the tracks to drop multiple inches. GSI® launched multiple soil nails into the embankment to provide additional shear resistance for the dynamic loading of the passing trains and to prevent future failures. The Soil Nail Launcher™ provided an expedited installation, reducing track time and permitting regular train flow. Over the coming years, TTCI research staff and GSI® engineers will perform in-depth instrumentation, monitoring, and analysis of the slope to determine optimal installation parameters.
A major roadway in California’s Bay Area presented a multitude of challenges to the state’s Department of Transportation where a large 140-linear foot portion of bluff supporting the roadway was simply sliding out to sea.
