Geocells Reinforced with Geogrids is the Winning Solution for Repairing Landslides in Hawaii
Six landslides occurred on military service roads during a 40-day rain storm in 2006. Surface water runoff on the roads triggered embankment failures in clayey silt fill soils and saprolite. When the USACE advertised the design-build project, their conceptual repair only considered structural walls supported with vertical piles. The selected design-build team determined that mechanically stabilized earth (MSE) walls could be constructed less expensively, quicker, and more safely than cast-in place walls resting on steel piles. The project saved 1.5 million (approximately 50% of the project cost) by constructing MSE walls with cellular confinement (geocell) facing and geogrid reinforcement, instead of the conceptual design provided with the Request for Proposal (RFP) documents. Geocells were selected as the MSE wall facing due to their light weight, ease of installation with relatively small construction equipment, tolerance to differential settlement, and cost compared with traditional pre-cast products and cast-in-place construction methods Additionally, the green geocell facing blended into the lush tropical vegetation of the ravine.
