Slopes along the highway, especially in hilly areas, are highly susceptible to landslides. Several factors such as heavy traffic and abundant rainfall during monsoon can contribute to slope failure. The slope failure can lead to damage to the mankind and the property. To mitigate risk associated with slope failure, different slope stabilization techniques, such as anchors, anti-slide piles, reinforcement, geotextiles, terracing, vegetation, soil nailing, can be adopted. Therefore, it is essential to conduct slope stability analysis for assessing the safety of slopes or embankments and also for the selection of most suitable stabilization technique before commencing any construction activities. In the present study, deterministic 2D slope stability analysis has been performed for a specific slope in Agumbe ghat, Karnataka and another landslide prone region in Dhobighat, Hyderabad. Both slope stability analysis has been performed using limit equilibrium analysis (LEA) and finite element analysis (FEA). Both slopes are found to be unstable according to LEA and FEA. Further, using anchors the slope has been stabilized and the factor of safety (FOS) increases in both FEA and LEA. In addition to that parametric study has been carried out to determine the effect of the design parameters on 2D slope stability analysis using LEA. It has been found that the slope at Dhobighat, where well graded sand is predominant are more affected due to the changes in the design parameters as compared to Agumeb ghat slope, which mainly consisted of stiff clay. The study also concludes that for a specific slope FEA provide more conservative FOS value compare to LEA.
