Based On The Combined Effect Of The Prestressed Anchor Cable Anti-slide Pile Design Analysis

Anti-slide pile with prestressed anchor cable is a new pattern structure which is widely used in slide-resistant engineering. Yet the code and theory for it's designing are not well established. This thesis analyzes the combined action of the pile and anchor system and generalizes the methods that are presently used, it also develops the optimization designing theory and methods for anti-sliding pile with prestressed anchor and does a optimization design for a specific anti-slide engineering using ANSYS soft.To establish a proper designing flow path for pre-anchored anti-sliding pile and understand the optimization paths and methods, the thesis analyzes the deliver process of slide thrust in the slope and onto anti-sliding pile as well as the anchoring mechanics of prestressed anchor cable. It obtains the computation formula for maximal anti-sliding pile space interval and the anchoring force formula. The thesis analyzes the landslide thrust computation methods and their applicability, develops proper distributing form on the pile of landslide thrust. It also works out a program to calculate the landslide thrust according to the delivering factor method and provide quantity load for pre-anchored anti-sliding pile designing. The thesis generalizes the present designing procedure and methods for pre-anchored anti-sliding pile, analyzes the irrationality of them and achieved a new mechanical model for anti-sliding pile with prestressed anchor cable which is more anastomotic to the realistic structures. It also gives a proper flow path for pre-anchored anti-sliding pile designing. At last, the thesis chooses a specific anti-sliding engineering which is under construction to be the example and optimize its anti-sliding design, it gets the proper anti-sliding resistant system and proofs the rationality of theory studying foreground.
