Laminar formation of sliding bed is usually regarded as equivalent with homogenate in current study of anti-sliding piles. However

this equivalent will definitely lead to some errors compared with real condition. Here

based on the deflection differential equation of the laterally loaded piles

the formulas of the displacement

internal forces and the stress of the elastic anti-sliding piles is deduced considering the different foundation coefficient of sliding bed. Meanwhile

the calculation and graphic processing programs of the internal forces and stress of the elastic anti-slide piles are written in Matlab software. This software devotes much in increasing the efficiency and the accuracy of the calculation. Comparisons were made with the method of equal effects to show that the displacement of sliding surface

the corner of sliding surface

the maximum values of the shear strength and the bending moment increases 25.76%

18.04%

15.6% and 4.39%

respectively

and the lateral stress of sliding surface decreases 44.91%. The study plays an important role in guiding different lithological rock masses of landslide for anti-sliding piles design.
