Abstract

The method of geosynthetic reinforced earth incorporates a flexible but tension resistant synthetic material in soil to increase the tensile resistance of the composite. In this study, both static and dynamic responses of an Ottawa 30-40 sand reinforced with a nonwoven geosynthet1c, Bidim C-34, were investigated. Static triaxial tests were first conducted to examine the influence of the reinforcement on strength, Young's modulus, and Poisson's ratio of the composite soil. Cyclic triaxial tests and resonant column tests were then conducted to examine the variation of shear modulus and damping ratio at different strain amplitudes. The influence of geosynthetic on both static and dynamic properties of sand was discussed.

Behavior of a Geosynthetic Reinforced Sand

St. Louis, Missouri

The method of geosynthetic reinforced earth incorporates a flexible but tension resistant synthetic material in soil to increase the tensile resistance of the composite. In this study, both static and dynamic responses of an Ottawa 30-40 sand reinforced with a nonwoven geosynthet1c, Bidim C-34, were investigated. Static triaxial tests were first conducted to examine the influence of the reinforcement on strength, Young's modulus, and Poisson's ratio of the composite soil. Cyclic triaxial tests and resonant column tests were then conducted to examine the variation of shear modulus and damping ratio at different strain amplitudes. The influence of geosynthetic on both static and dynamic properties of sand was discussed.
