Abstract
ABSTRACT: The stability of soil slopes can be significantly increased as a result of the in situ stabilization technique of anchored geosynthetic systems (AGS). An experimental study was performed on AGS sandy slope models with different cross-sections and subjected to uniform seepage. The slope models were brought to failure by gradually decreasing the AGS loads. A comparative analysis of the failed models in terms of the predicted safety factors and slip surface configurations were carried out using limit equilibrium and finite element analyses. Good agreements were obtained between the experimental and theoretical predictions in terms of the failure surface configurations as well as the safety factor at failure. Surface load applications on homogenous, granular slopes tend to change the failure mode from a planar slide assumed by the infinite slope theory to a more rotational sliding.
