Flexible slope stabilization systems made from wire meshes in combination with nailing are widely used in practice to stabilize soil and rock slopes (Fig. 1). They are economical solutions and a good alternative to measures based on rigid concrete liner walls or massive supporting structures. Apart from designs using conventional steel wire, meshes from high-tensile steel wire are now also available on the market. The latest can absorb substantially higher forces and transfer them onto the nailing. Special concepts have been developed for the dimensioning of flexible surface stabilization systems for use on steep slopes in more or less homogeneous soil or heavily weathered loosened rock, but also on fissured and layered rock in which the bodies liable to break out are determined by fissure and layer surfaces. Stabilizations implemented in soil and rock, with and without vegetated face, confirm that these measures are suitable for practical application (Cala, et al. 2012). The research work presented in this paper explains the latest verification of the existing dimensioning concept for superficial slope protection system based on test results coming from a large-scale field test setup. Thereby the influence of properties of the facing as well as deformations under loading and forces on the nails are tested and the results will be presented.
