Abstract: The calculation of anchor cable antislide pile has not considered the interaction between the pile and the landside by the traditional methods. It only considers the pile above the slidesurface as static structure or finite statically indeterminate structure. Based on elastic foundation beam theory and considering deformation compatibility of the anchor cable and pile,this paper applies the initial parameter method to the calculation of anchor cable antislide pile. By selecting reasonable initial parameters as the unknown variable,this paper has deduced the calculation steps of the pile,including the tension force of anchor cable and internal forces of the pile. Applying this method to the treatment of bedding landslide controlling engineering in one project and comparing with the traditional method,this new method is shown to be safer and agrees well with the results using the traditional method．
