Slope stability optimization using reinforcement by GEOSLOPE

This paper is studying slope stability evolutions by limit equilibrium (LE) methods and compared with the results from GEOSLOPE software. The LE based methods are compared based on the factor of safety (FOS) obtained from various conditions with simplified slope geometry and assumed input parameters. Specified slope is modeled in two various conditions; dry and wet, subjected to nailing and anchor reinforcements. Then, reinforced models are compared to the unreinforced samples in order to investigate the factor of safety of slope stability. Using reinforcements can increse the factor of safety of slopes to 30percent.The comparative study among the LE methods showed that BSM is as good as M‐PM for normal condition in circular shear surface (CSS) analysis whereas simplified Janbu (JSM) method gives the most conservative value of the FOS. It is suggested that using anchors in practice due to long fixity and high efficiency so as to increase slope stability
