Abstract

    Geotechnical parameters is of one of the most important indices on the topics of engineering geology. Therefore, the purpose of industrial development and structural, geotechnical engineering and geological information provide a comprehensive database is essential.The permeability is one of the most important physical properties of soil that has been used in geotechnical engineering. Soil permeability generally depends on two factors, one factor is soli properties contains porosity, The surface roughness of solid particles, Saturation and another factor is fluid (water) properties which passes through the soil. In order to do research The design and testing device for measuring horizontal and vertical permeability In the case of coarse particles. In this study, three non-uniform samples is selected for test. The results show the permeability anisotropy for non-uniform sample is between 1.32-3.5 also with increasing the uniform coefficient the rate of anisotropy permeable decreased. Also in the non-uniform samples with the increases percentage of fine particles (particles with a diameter smaller than 4.75 mm) decreases the permeability anisotropy. According to results The use of fine particles in the implementation of various schemes marine structures is recommended.
