Design aspects of segmental crib retaining walls

The widespread use of segmental crib retaining walls has been limited by uneconomical and conservative design processes. The Coulomb theory commonly used to predict performance does not take into account the flexible nature of the walls, which allows stress redistribution away from critical locations. Full scale testing and laboratory modelling have indicated that the use of Coulomb's theory, with wall/soil friction equal to the internal friction of the backfill soil, provides the best approximation of crib wall behaviour. Such a design approach can allow up to a 15 percent increase in wall height but is still conservative, especially for walls with height to thickness ratios less than about five.
