Geotextiles used in reinforcing walls, berms, and slopes

Reinforcement use of the stress-strain behavior of a geosynthetic material to improve the mechanical properties of soil or other construction material. 

Reinforcement mechanisms Within the general function of the geotextile reinforcement of sods, there are three different types of reinforcement mechanism membrane, shear, and anchorage. 

Shear type Shear reinforcement can be better visualized by means of direct shear tests. Here, a geotextile placed on a soil is loaded in a normal direction, and then the two materials are sheared at their interface. The resulting geotextUe-to-soil shear 

Strength parameters (adhesion and friction angle) can be obtained as described in a traditional geotechnical manner using an adapted form of the Mohr—Coulomb failure criterion (Eq. [15.1])  

The shear strength parameters Ca and 8 can be compared with the shear strength parameters of the soil by itself (ie, soil against soil) as follows (Eq. [15.2])
