Numerical Study on Cyclic Shear Behavior of Soil–Geosynthetics Interface
Abstract Geosynthetics are being widely used as a reinforcement material in the construction of mechanically stabilized earth (MSE) walls. The strength and stability of these walls are depending upon the interface behavior between soil and reinforcement material. It is understood from the literature review that the dynamic interface properties of soil and geosynthetics are not well explored yet, as in the case of static loading conditions. The present study investigates the cyclic behavior of the interface between sand and non-woven geotextile material. The objective was achieved by simulating the cyclic direct shear test using finite element-based package PLAXIS2D. The behavior of interface shear stiffness, and damping ratio were studied with increase in number of cycles and displacement amplitude. In addition, the interface behavior of geotextile with the sand having different fines content was also studied. The results revealed that the increase in the fines content causes the reduction in the interface shear stiffness. The interface shear strength properties obtained from the cyclic direct shear test were compared with the static shear test. The friction angle obtained from the cyclic shear test was 6% higher than that obtained from the static direct shear test.
