MODERN FLEXIBLE SYSTEMS FOR SLOPE STABILIZATION MADE FROM HIGH-TENSILE STEEL WIRE MESHES / NETS IN COMBINATION WITH NAILING AND ANCHORING IN SOIL AND ROCK

Abstract

Flexible slope stabilization systems made from steel wire meshes and spiral rope nets in combination with nailing are widely used to stabilize soil and rock slopes. 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 latter 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 jointed and layered rock in which the bodies liable to break out are determined by joint and layer planes. Stabilizations implemented in soil and rock, with and without vegetated face, confirm that these measures are suitable for practical application.
