DESIGN OPTIMIZING OF ANTI-SLIDING PILE WITH PRESTRESSED CABLE ANCHORS

The technique of anti-sliding piles with prestressed cable anchors is an effective measure in landslide treatment.Compared with common anti-sliding piles,anti-sliding piles with prestressed cable anchors result in a more reasonable force bearing state.This paper,on the basis of simple hypothesis,presents the physical model and computing diagram of piles with with prestressed cable anchors,derives the anchor in the pile body free position formula,establishes a simple procedure realization moment and stress computational scheme.This method can be used to determine the most superior anchor angle and the most superior position,which will effectively reduce the anti-slide pile moment and fully display anchor function.Finally,a case of the BaoTa mountain of Yanan landslide treatment is given and the practical result is discussed.
