Parametric Study of the Stabilization of Sloped Surfaces Bedding with Geotextiles
One of the most important applications of geotextiles is as a reinforcement to increase the stability and strength in soil slopes as well as to stabilize slopes which would be unstable without reinforcement. This paper presents the results of a parametric study which investigated the effects of various factors, such as the number of reinforcement layers and a dike’s slope angle, on the dike�s safety factor. Using PLAXIS software and the finite element method, the maximum final displacement, maximum horizontal displacement, maximum vertical displacement, and maximum shear strain which are created in a dike were examined. The results show that as the number of reinforcement layers was increased, the dike’s safety factor increased and the maximum final displacement, maximum horizontal displacement, maximum vertical displacement and maximum shear strain created in the dike decreased. Furthermore, as the dike’s slope angle increased, the safety factor of the dike’s stability decreased and the maximum final displacement, maximum horizontal displacement, maximum vertical displacement, and maximum shear strain created in the dike increased.
