Study on Interaction between Mini-Pile and Slope under the Effect of Overloading

Analysis interaction between mini piles and vertical slope under the action of overload, discusses the influence on mini pile and slope under different condition such as pile length,pile diameter and so on. The results showed that: (1)with the micro-pile length increases, bending moment of pile increase present a trend of increase, pile lateral displacement and the displacement of the slope decreases; (2)with the increase in diameter of micro-pile, bending moment increases, the lateral displacement of pile decreases, the slope of the displacement decreases; (3)with pre axial force of soil nails increase, bending moment of pile decreases, the lateral displacement of the pile decreases, the slope of the displacement decreases.
