  • This paper takes the basic form of double-row cantilever beam anti-slide piles without joist as the model.Based on structural analysis theory,it presents the equations for calculating the transferring push force and the distribution between the double-row piles..It further uses the Hongshibao landslide as a case study for analyzing the double-row pile static row spacing,the section size of back and front piles,and the soil elasticity modulus between piles.It examines their influences to the thrust force distribution.Conclusions from the examination are obtained as follows: (1)When either the rigidity of the back pile increases or the rigidity of the front piles decreases,the extrusion interacting force between the soil and the two-row piles decreases,A2/A1 decreases along with it.Otherwise A2/A1 increases.(2)When the row distance b increases,A1 decreases,A2 decreases gradually when b=3 to 10m; A2 increases when b=10 to 21m. (3)When increases the elasticity coefficient between piles,A2 increases.(4)Along with the increases of the section high of the front piles,both A1 and A2 increases gradually; along with the increases of the section high of the back piles,both A1and A2 decreases gradually.
