Abstract: The distribution mode of landslide thrust on anti-sliding piles directly determines the internal forces and their distribution characteristics over the piles. So it has an important effect on the reasonability of design for the anti-sliding piles. Considering real design conditions for the anti-sliding piles in a practical project, pressure formulae of the landslide thrust are provided approximately by the limit equilibrium analysis on differential horizontal layer of sliding body in soil-like slopes or landslide projects. The formulae indicate that the distribution mode is parabolic along the longitudinal axis of direct anti-sliding segment of the pile with smaller value at its two ends than that at its middle part. The results of laboratory model tests on the limit status of sliding body movement show the approximate theoretical method given is realistic.
