Abstract
Abstract The interaction between soil and geosynthetic reinforcement is important for the design and performance of reinforced soil structures. This interaction can be very complex depending on the type, properties of the reinforcement and orientation for these geosynthetic into a reinforced soil. The interaction mechanism for different orientation of these geosynthetic still doesn’t study accurately. This paper investigates the interaction mechanism for reinforced sand with different geosynthetics types at different inclination angles. The strength parameters of soil geogrid interface were obtained from direct shear tests. Two types of geosynthetic, Woven geotextile and Biaxial geogrid were selected to insert into sand. Laboratory testing program were performed in shear box device, square box with 100 mm in length was used and the reinforcement layer was placed in different inclination angles. The first angle is perpendicular to the failure surface 90. the second angle of reinforced was inclined with 45. to the failure surface and the third angle of reinforced was horizontally parallel to the failure surface. All tests were conducted with three vertical load 17.95, 27.95 and 37.95 kg. Three parameters were studied according to the relative density of sand, inclination angle of geosynthetics in shear box and type of geosynthetics reinforcement layer. The test results reveal that the sand reinforced with biaxial geogrid achieved the highest value of shear strength enhancement. The maximum shear strength improvement occurred at inclination angle 90 to the failure plan when reinforced by biaxial geogrid and Woven geotextile.
