• Description:
  Analysis, design and testing of independent reinforced concrete facing panels for mechanically stabilized earth (MSE) walls are reported. Panels are intended for use as full height facing for a variety of mechanical reinforcements for fills including geotextiles, geogrids, and bar mats. Panels provide a forming surface and permanent facing for MSE walls, but are independent of the MSE mass. Panels are attached to stable MSE constructions with flexible anchors that limit earth pressures on panels. Loads on panels are minimal, and panel size and appearance may be tailored to the requirements of individual projects and sites. This offers options in construction operations and in appearance of the finished wall not previously available for MSE constructions. This report presents the basis for design of independent facing systems, presents methods for stress analysis of independent facing panels, reviews options for full-height and for stacked panel facing systems, outlines construction procedures for MSE walls with independent facing, and presents options for anchors and panels for independent facings. The report also presents the design, fabrication, testing and performance of a prototype independent facing panel used in MSE wall tests.
