The friction between the filled soil and the reinforcement materials can not only transfer to reinforced material tension but also can prevent the development of the soil’s lateral deformation.
When stiffened by pull force, the frictional resistance will prevent the reinforcement material be plucked up.Therefore, as long as reinforcement materials keeping a enough strength and enough friction, the reinforcement of the soil can balance stable.
Consideried the reinforced structure as a whole, the reinforced structure can be regarded as a anisotropy of composite materials.
These materials can be isotropic or orthogonal anisotropic linear elastic material and no destroy limit.The geogrid has a shearing friction with the soil surface in the cutting plane direction,but in normal direction is attached to the grid.

However, less attention has been given to the machinability of these materials.

Introduction In order to adapt to the high-speed, heavy-load, light-weight development demands of railway transport, the materials which used in the vehicle must have great innovation.
According to the extraordinary superiority performance of the macromolecule materials, such as, plastic, engineering plastic, rubber, fiber et al, and composite materials will be more widely used in the field of the vehicles[1].
Therefore, selecting appropriate retainer materials, structure and molding process has become the key to improve the property and reliability of high-speed vehicles bearing[2].
When the materials flow from all directions toward one single node, the air trap is generated.
