FEM comparative analysis of facing rigidity of geotextile-reinforced soil walls

The deformation behavior of geotextile-reinforced soil walls with two types of comparatively rigid facings (made of concrete panels and concrete blocks) and that of a geotextile-reinforced wall with a wrap-type facing, the latter having many records of construction to date, were numerically analyzed through a two-dimensional elasto-plastic FEM, and the effect of the facings was evaluated through comparative study from various aspects. As the result, some findings were obtained about the constraining conditions for comparatively rigid facings to exhibit the effect of restraining the deformation of reinforced walls and about constructional measures to satisfy such constraining conditions.
