Abstract

For any structure in steep places, to function properly, a slope stability analysis must be conducted to understand the behavior of slopes. This paper is concerned with slope stabilization by two different techniques, berming and soil nailing. Analysis is performed by adopting the software (Plaxis 2d) to investigate the effect of different parameters on the behavior of slopes. The examined parameters in soil nailing technique are summarized as, the nail length, the angle of nail inclination with the horizontal, the spacing between nails. For berming technique, the influence of the berm width, the berm height and the berm inclination. In the present study, the slope performance is measured by identifying the factor of safety against slope failure. The results indicate that while soil nailing offers advantages in terms of flexibility, rapid installation, and minimal footprint, berm construction excels in providing robust lateral support and erosion control. Moreover, considerations of cost-effectiveness, maintenance requirements, and environmental impact play a crucial role in selecting the optimal stabilization strategy for specific slope conditions. Overall, this comparative study contributes to the advancement of geotechnical engineering practice by offering insights into the strengths and limitations of soil nailing and berm techniques in slope stabilization.
