Recent Experiences of Reinforced Soil Retaining Structures in China - Reinforced Soil Engineering: Advances in Research and Practice - page 160

In the past 10 years, the application of GRS retaining walls in China has
developed to include the following:
1. A retaining wall with a height of 35.5m
2. Reinforced bank with two opposite walls
3. Reinforced soil pier and abutment of bridge
4. Bearing the horizontal pressure on a box foundation
Some related research of tests and design methods includes:
1. Influence of modulus of reinforcement and measurement of earth
pressure
2. Properties of fiber-reinforced cohesive soils (FRCS) and centrifugal
model tests of FRCS in steep slopes
3. Prevention of frost heave of GRS retaining wall
4. Pullout of geotextile in various directions and stability analysis
The above topics are the focuses of this chapter.

2.1 Stability Analysis of Reinforced Soil Structure in
Consideration of Direction of Geotextile
By using the test device shown in Fig. 1, one can conduct a series of pullout tests
on geotextile in various directions. In the device, a metal sliding plate can slide
along two rails and change its direction, and a top plate with an air bag can apply
