Cracks of irrigation channel’s service roads are becoming a significant feature in Al-Ghab region. All information indicates that lateral spreading of stresses in slope vicinity induced cracks in the side parts of roads. These cracks resulted from la
teral displacements, which could dominate total displacements. This
paper presents a geotechnical evaluation of the possibility to mitigate this phenomena by using geogrid soil reinforcement. Finite elements numerical model analysis is performed to calculate total, horizontal and vertical displacements at road side near channel’s slope. Numerical models include different cases of
un-reinforced soil and geogrid reinforced soils at different locations. Locations of geogrid were chosen carefully to attain the best effectiveness. Beneficial factor and coefficient of efficiency were determined for reinforced road.
This research study aims at investigating the potential benefits of using the
reinforcement to improve the bearing capacity and reduce the settlement of strip footing on
clay. To implement this objective, many numerical 2D-analyses by finite elemen
t method /
Plaxis program were performed to study the behavior of reinforced soil foundation. And
then we carry out a parametric study of the most effective parameter on bearing capacity.
The results showed that the inclusion of reinforcement can significantly improve the soil’s
bearing capacity and reduce the footing settlement. The strain developed along the
reinforcement is directly related to the settlement. The results also showed that the
inclusion of reinforcement can redistribute the applied load to a wider area, thus
minimizing stress concentration and achieving a more uniform stress distribution. The
redistribution of stresses below the reinforced zone can result in reducing the settlement of
the underlying weak clayey soil.
