The original anchor retaining wall construction finished and in use for some time,due to unfavorable factors not considered in the design of comprehensive, qualityconstruction process of construction is not well controlled or not in accordance with theconstruction process of construction, in the course due to human or natural after thefactors that led to the original anchor so partial failure, and the failure of the bolt can notbe repaired to restore its resistance and therefore can not be used normally;This failuredue to anchor cannot continue to provide resistance to constrain the slope deformation,and the bearing capacity of anchor can not increase will lead to less than the slope forceof anchor anti slide down.Therefore, the slope stability coefficient and safety coefficientare not up to the specified requirements,which shows that the slope exists hidden safetyproblems, if the slope in the more unfavorable factors may slide and collapse.Which showing that the failure on the part of anchor bolt retaining wallreinforcement is very necessary and important.On the slope reinforcement, whether it is pre-stressed reinforced or non-prestressedanchor bolt reinforcement must first determine the slope of the displacement anddeformation can be reinforced. We have not found theories about the derivation of slopedisplacement, in which we use elastic mechanics to solve the slope displacement, andgives the under the action of gravity, the top load and anchor of the slopedisplacement.On the basis of the research part of the bolt failure of the slope afterreinforcement.Bolt retaining wall slope in supporting widely used today, there areanchor bolt retaining wall supporting part failure, and this phenomenon is widespread,and the current portion of the bolt after the failure of either study calculated from thetheory of reinforcement design method, using the form of reinforcement to determinewhat aspects are rarely. Therefore, this paper proposes the use of non-prestressedreinforcement and prestressed anchor bolt reinforcement methods and calculationmethodsThis paper is an anchor retaining wall supporting a relatively mature theoreticaland experimental conclusions for the latter part of the non-prestressed anchor boltfailure problem reinforced and prestressed concrete anchor reinforcement,in-depthanalysis of deformation of anchorage section, displacement and slope in the later part ofbolt failure slope combination, established by the non prestressed anchor calculation model of reinforcement and prestressed anchor, and numerical simulation analysis bySLOPE program for computing model correction adjustment, summed practical designcalculation method of prestressed reinforcement bolt. Finally, through the projectexample indetail two reinforcement concrete methods of calculating process, but alsoembodies the two reinforcement method is practical.
