On the basis of in-situ survey and landslide controlling design
a contact FEM program using contact elements is designed in the light of the characteristic of the interaction between piles and soils. Then
the anti-sliding effectiveness of prestressed cable piles is evaluated according to the calculation results of such factors as force-bearing distribution
pile shaft bending moment
displacement and prestress etc. Finally
an optimum prestress value for prestressed anti-sliding cable piles is suggested
which is of significance for guiding engineering design to a certain degree.
