Abstract
Mechanical behavior of reinforced soil by continuous fibers is examined by means of three types of soil tests. According to the test results, effect of fibers mixing into the soil comes out as apparent cohesion of the soil and magnitude of it depends mainly on mixing ratio of the fibers. Degree of tension of the fibers in the soil and relation between size of particles of the soils and thickness of fibers have also great influence on the value. Reinforced soil by continuous fibers have an anisotropic behavior concerning the shear strength, which is induced by mixing process of fibers into soils. Influence of the fibers on coefficient of permeability of the soil is almost negligible.
