On the design of nailed retaining walls

Nailed retaining walls are composites consisting of soil and steel rods. They act as retaining walls and resist earth pressure. Usual design methods are based on the consideration of rigid block failure mechanisms, where the shear band and the nails intersect at nearly 90°. However, this mechanism cannot mobilize tensile forces in the nails, what is contradictory to the assumption of the existing methods. We propose a new design-method which is based on the consideration of stress within the composite and, thus, removes the afore mentioned contradiction.
