Influence of Surcharge Loading on Seismic Response of Nailed Soil Slopes
Slope stabilization using soil nails is implemented in homogenous soil slope subjected to seismic loading and considering a planar failure surface passing through toe of the slope. Closed form expressions, for determining the equivalent pullout capacity of the nails and factor of safety, are proposed considering the influence of surcharge load, seismic forces, angle of the failure plane, slope angle, inclination angle of the soil nails, and spacing between the nails. It is seen that the increase in soil nail inclination angle increases the equivalent pullout capacity of the nail and the corresponding failure angle of the wedge. An increase in horizontal spacing between the soil nails reduce the equivalent pullout capacity of the nails and angle of the failure wedge. The simplified trial wedge method serves as an accessible method for initial analysis of nailed soil slopes and also a check on advanced methods employing complex techniques to compute the factor of safety at critical conditions. The proposed design charts will be fruitful for geotechnical engineers in assessing the stability of nailed soil slopes in earthquake prone areas.
