Soil Fiber Reinforcement
The action of roots in nature demonstrates the basic principles of soil
reinforcement. So the concept of fibre reinforcement is analogous to the
reinforcement of soils with plant roots. The fiber reinforcement idea has
become important for use in engineering construction activities following
the root reinforcements. The effect of root reinforcement on the shearing
resistance and the slope-stability of slopes in nature have been reported
by several investigators. The clay bricks reinforced with reeds or straw have
th been used in the 5 and 4th centuries BC. Ziggurrat of Agar-Quf
(Baghadad) is the earliest examples of soil composite. Plant or grass
reinforced clay bricks were used for construction of the Agar-quf
Ziggurrat, while the Great Wall of China was made from mixtures of
tamarisk branches, though the mechanism was not clearly enunciated.
