Abstract:
It is a comprehensive analysis on various experimental and numerical studies on slopes. Small scale physical modeling of slopes under surcharge loads was performed on loose sand slopes. Digital image was captured during the incremental loading from the model’s side. Particle image velocimetry and 3D numerical model were applied to investigate the slope under surcharge loading: several important factors that control pile performance are investigated. safety factors and location of slopes are obtained and compared. The results show, the 3D failure surface of various reinforced and unreinforced slopes are obtained and compared. The results show, the 3D failure surface shape in front of piles is from its conical shape in laterally loaded piles.
This paper also analyzes the effect of soft bound interlayer, soil properties, pile spacing, pile position, and surcharge distance on the safety factor and slip surface shape of the stabilized and non-stabilized slopes. The results indicate that the distance of soft soil layer from ground surface and its horizontal direction angle strongly influence the optimum location of the piles. The numerical modeling results show that increasing the distance between the piles prevents instead, increases the failure volume in the slope.
