ANALYSIS OF GEOTEXTILE EMBANKMENT BY ANSYS
Main Article Content
Abstract
The major objectives of this research are to analyze the behavior of road embankments
reinforced with geotextiles constructed on soft soil and describe the finite element analysis by using
ANSYS program ver. (5.4). The ANSYS finite element program helps in analyzing the stability of
geo- structure (embankment) in varied application of geotextiles reinforcement to enhance the best
design for embankment.
The results of analysis indicate that one of the primary function of geotextiles reinforcement was to
reduce the horizontal displacement significantly. With the inclusions of reinforcement, the horizontal
displacement reduced by about (81%), while the vertical displacement reduced by (32%). The effect
of geotextiles stiffness modulus on horizontal and displacement is quite significant even a very high
modulus of geotextile will have relatively little effect on vertical displacement. Also it is observed
from the obtained results that the maximum displacement occurred at the toe of embankment for both
horizontal and vertical movement, then decrease gradually to a negligible value for the layer
reinforced case. Also the reinforcement reduces the shear stress developed in the foundation soil.
