Prestressed Anchor Friction Pile Internal Forces Analysis Of Experimental Research And Numerical Simulation

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 is based on the construction monitor of anti-slide pile with prestressed anchor cable.through the test study of the anti-slide pile with prestressed anchor cable and the calculation procedure of internal force of design methods.at last.combining the specific anti-slide pile engineering and use ANSYS software to calculate the deformation of slope and the internal force during the course of the construction.Firstly,the analyzes the stability methods and the deliver process of slide thrust in the slope.about the slope stability,have two different methods to analysis the problem and for the different slope cases choose the specific methods .about the deliver process of slide thrust.discuss the principle.that is the methods of stability of slope are match to the calculation of optimization paths and methods and onto anti-slide pile as well as the anchoring mechanical of prestressed anchor cable.secondly,the thesis discuss the design methods,principle and the design order in the anti-slide pile with prestressed anchor cable,including the methods of calculation of internal force.thanks to the course of prestress forced so require the dynamic design in the course of construction.and through the research.it abtains the phrases of dynamic design in the anti-slide pile with prestressed anchor cable.thirdly,thesis combining the high slope treatment engineering which belongs to the MOUTAI factory.the test of study on spot had done during the course of construction,through monitoring the tense force of prestressed cable displacement and internal force of the pile.it abtain the methods which avoid and reduce the loss of prestress in the anti-slide pile and prestressed anchor cable.at last,the thesis choose this specific anti-slide engineering which is under construction to be example .build the finite element methods to calculate the slope displacement and internal force in anti-slide pile during the course of construction.it abtain the results and compare with the actual.the methods of design and internal force including the procedure is proposed.
