Innovative Repair of Failed MSE Walls Using Geosynthetic Materials In Conjunction with Strength Elements – Will Brantley, PE

Mechanically Stabilized Earth (MSE) and steel pile walls are commonly used throughout the United States to repair landslides and create favorable site and road prism geometries. However, when improperly designed, these structures have an associated failure rate of 5%. Post-failure reconstruction and remediation often present challenges beyond those encountered during original construction, including difficult site access and critical infrastructure maintenance, and roadway traffic. Using case studies from five recent design/build MSE and pile wall repair projects in the Eastern United States, this presentation outlines some of the new and innovative methods available to designers. These methods are robust enough for structural repair and specific enough to prevent unnecessary impact to roadway users and critical infrastructure disruption. Relevant technologies include traditional soil nailing, reinforced architecturally sculpted shotcrete, reticulated micropile arrays, and Geosynthetically Confined Soil (GCS®) walls constructed with lightweight recycled aggregate.
