An Application Research On Prestressed Anchor Cable In High Slope Of PuTan Highway

In the process of the design and construction of the slope, we have beenhaunting the stability of slope. Therefore, reasonable evaluation slope stability is torealize the basis for the control of design and construction. If the slope stability isinsufficient, it must be the reinforced, and the prestressing anchor technique slopereinforcement is a more extensive, more applicable method.Combining with the actual prestressed anchor slope reinforcement project of theprestressed anchor mechanism, design and construction are discussed.Firstly the slope stability research situation at home and abroad and theprestressing anchor (stem) reinforced slope the present study status of the detailedreview. Secondly, theoretically in strengthening the mechanism of the slope ofprestressed anchor is discussed in detail, and specifically including the principle ofprestressed anchor slope reinforcement, physical and mechanical effect, prestresschange mechanism, etc. Again, through the introduction of the numerical analysismethods in the application of slope engineering, and combined with engineeringexample, a cutting slope of analysis, and limit equilibrium method, comparing thecalculation results are close to each other, once again, show that the slopereinforcement design is reasonable. Finally, this paper discusses the slope ecologicalmeasures of prestressed anchor, used in the design of the slope, already beautificationenvironment, on the slope stability and has some effect. The research results can forthe slope of the prestressed anchorage technique designed to provide the beneficialreference.
