A Parametric Study of the Behavior of Geosynthetic Reinforced Soil Slopes

Abstract

This paper presents the results of a number of computations using the 2D FEM to show the effects of significant variables on the behavior of geosynthetically reinforced earth slopes. The verification and reliability of the results are primarily examined through comparisons with experimental data available. The results seem to be quite acceptable and can be used with a high degree of reliability for predicting the relevant problems.The main variables studied are soil properties, slope geometry, and the properties of reinforcement elements, while the safety factor, deformation components, effect of geotextile stiffness, the shape and location of the slip surface are the main unknowns sought.
