Geo Barriers

  1. 1. 40+ YEARS AND 25,000,000FHWA, UNIVERSITY AND DOT RESEARCH
  2. 2. gcsBarriers™ are anotherextension of the powerfulGCS™ technologies
  3. 3. gcsBarrier™ On Duty The Colorado RockfallSimulation Program (CRSP) was used to determineheight of this gcsBarrier™. Note the slope grading uphill of the gcsBarrier™to control bounding heights of incoming rocks
  4. 4. Designed byTerraTech Consulting, LTD Salmon Arm, BC9 inch geofabric spacing
  5. 5. gcsBarrier™ by Linda BarrettTHE DESIGN ROCK
  6. 6. gcsBarriers™ StopThe Little Rocks
  7. 7. gcsBarriers™ Stop5 million foot pounds!!! The Big Ones They Stop Anything That Does Roll Over Them Cameron Lobato
  8. 8. Design and Construction of a gcsBarrier™ is the same 1, 2, 3 processused for Walls, Abutments, Piers and Deflection barriers ---Two rows of CMUs, a lift of granular backfill and a sheet of geofabric.
  9. 9. More Construction Photos Research and DemonstrationIndicates a .6 ratio Base/Height is Sufficient
  10. 10. Negative Batter Improves Rock Stopping CapabilityTed Ruckman
  11. 11. Elegant Combination of a GCS™ Box Culvert Design As a Portal for a Mine Entry AndAn Elevated, Thickened GSC™ Wall as a gcsBarrier™ for Rockfall Protection
  12. 12. ROCKFALL PROTECTION ON I-70Designed by Barrett for Colorado DOTThis GCS™ Wall is 26 feet high and hasA 30 foot wide rockfall catchmentBench on top.This GCS™ Wall has a truncated base.The bottom geofabrics are only3 feet wide, and progress to 30 feetat the top. Very efficient – unlike MSEwe avoided excavation of bedrockat the base.This wall was carefully monitored.Shown here is CDOT’s John David –john.david@dot.state.co.us -CDOT’s project manager. Deflection wasLess than ½ inch and strains in theGeofabric were less than ½%, which isTypical for GCS™ performance.
  13. 13. INDEED,IT CAUGHTA ROCK!
  14. 14. 15 million Foot Pounds of Energy (it was nuked!)
  15. 15. ONLY MINOR DAMAGE
  16. 16. QUICK AND EASY REPAIR
  17. 17. OTHER APPLICATIONS MUDFLOW DEFLECTION
  18. 18. ROCK-FACED GCS™ FORAVALANCHE DEFLECTION
  19. 19. ROCK-FACED GCS™ FORAVALANCHE DEFLECTION
  20. 20. THIS SUITE OF SLIDES SHOWING gcsBarriers™ SERVES TO ILLUSTRATE THE VERSATILITY AND ADAPTABILITY OF THE POWERFUL GCS™ TECHNOLOGIES. THESE EXAMPLES ARE COMPELLING REASONS TO BEGIN THE TRANSITION FROM MSE TO GRS/GCS™ CONCEPTS. MSE WAS A TRANSITIONAL STEP AND IT HAS SERVED ITS PURPOSE.
