Back-To-Back Mse Walls-A Comprehensive Understanding

Mechanically stabilized earth (MSE) is one of the major geotechnical engineering innovations of the late 20th century. Invented in 1957 and first reported in 1963 by French engineer-architect Henri Vidal, after pondering the mechanics of sand and pine needles, his reinforced earth product revolutionized civil engineering and the construction of earth retention and support structures worldwide, offering dramatic structural, and economic advantages compared to previous design approaches. Now generically known as mechanically stabilized earth (MSE), a creative application of the technology is for back-to-back walls, hundreds of which are in service for roadway and pedestrian ramps, railway systems, and other applications.MSE walls, especially in a back-to-back configuration, are a significant innovation in geotechnical engineering and construction. This paper brings together elements of MSE theory and practice to provide a comprehensive understanding, enabling practitioners to best use this innovative technology.
