This study aimed to use numerical modeling to investigate the behavior of soil slopes under various inclination angles of soil nails and surcharge load conditions. Numerical modeling and analysis are performed using finite element software PLAXIS 2D. In this study, the stability of a soil slope is investigated at different soil nail inclination angles, viz., 0°, 5°, 10°, 15°, 20°, 25°, and 30°. A surcharge load of 80 kN/m is applied at distances of 2 m, 4 m, and 6 m from the slope edge. The results show that the safety factor increases with increasing soil nail angle under a constant surcharge load. Similar results were obtained when the distance of the surcharge load increased from the slope edge. In addition, the bending moment and shear forces in the soil nails decreased with increasing inclination of the soil nails and increasing distance of the surcharge load from the slope edge. The slope with nails at 20° is the most stable slope, with safety factors of 1.647, 1.610, and 1.692 for the three surcharge loads. Similarly, minimum shear forces of 2.298, 2.684, and 1.183 kN/m and bending moments of 0.4132, 0.4075, and 0.1236 kN-m/m are predicted when the nails are inclined at 20° for the above three cases of surcharge loading, respectively.
