    This paper deals with the reinforced slope stability analysis. It was assumed that soil profile of a slope consists of two layers. The strong soil (soft rock) is covered by weak soil (or weathered rock). Such slope geology determines the way of soil reinforcement. Usually nails or anchors are applied for to provide the overall stability of the slope. However the face reinforcement of soft soil must also be used. Generally, slope stability analysis for such case, is limited to nails or anchors interacting with the soil. The face reinforcement is usually not taken under consideration. The way of reinforcing the slope with pre-tensioned nails connected to wire mesh facing is described and applied. The nails are modeled by rockbolt elements, which can rupture. The wire mesh is modeled as beam element with resistance only in tension and connected to the soil by »unglued« interface. Factor of safety (FS) of a slope is calculated with shear strength reduction technique. Nails pre-tension were obtained by user-written FISH function. A series of FS calculations were performed to show, the wire mesh facing is not only local stability protection, but can significantly increase the overall slope stability.
