New Method for Calculating Deformation and Internal Force of Anchor Anti-slide Pile

Haiying Wang

Abstract

Combined with structural mechanics and elastic foundation beam theory,a new mechanics calculation model of anchor anti-slide pile was established considering the elastic deformation of anchor cable.In deducing the formula,the anti-slide pile was divided into top and bottom segments from the sliding surface.The bottom segment,which was embedded in the slip bed,was calculated as a elastic foundation beam,and the top section was calculated by force method.Using the deformation compatibility condition of pile section on the sliding surface,the calculation formula of anchor pile was established,and the formula was very convenient to solve anchor cable tension force,anti-slide pile internal force and deformation of the body.Finally,taking a landslide control project as an example,the anchor cable tension and pile internal force were calculated,the reliability of the method was verified,and the result was compared with that of ordinary anti-slide pile.
