Much of the research on the mechanism of geotextiles has identified limits for which the reinforcement mechanisms are considered to be effective. The influence of each mechanism tends to diminish with stronger subgrade conditions and as each additional... 

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

The key properties of geotextiles used in reinforced soil applications are introduced with short explanations. For details about the tests mentioned here, see chapters Hydraulic properties, behavior and testing of geotextiles Long-term geotextile degradation mechanisms and exposed lifetime predictions and Geotextiles used in separation. 

Conventional gravity and cantilever wall systems made from masonry and concrete resist lateral earth pressure by virtue of their large mass. They act as rigid units and have served the industry well for centuries. These mechanically stabilized earth (MSE) walls, which have geotextile reinforcement (Fig. 15.20), are flexible compared with conventional gravity structures. 

Reinforcement. Soil is relatively strong in compression, but very weak in tension. Therefore, if a tensile inclusion (geotextile) is added to the soil and forms an intimate contact with it, a composite material can be formed which has superior mechanical characteristics in...
