Reinforced soil shear stresses

Figure 15J Shear stresses in a reinforced soil element along a sliding surface.

In the case of Fig. 15.6, sliding resistance along a reinforcing element results from shear stress at the interface between the soil and the geotextile, which is given by (Eq. [15.15]) ... 

The factor of direct sliding varies depending on the nature of the soil and the structure of the reinforcement. Table 15.1 shows the recommended values for geotextiles. In the case of Fig. 15.7, the shear stress resisting pull-out is ...
