| Prestressed cable anti-slide pile that is set prestressed cable in the general anti-slide pile on the top of the pile or a certain location of pile , with cable provided by the anchor of the anti-slide pile and provided by the resistance by the two Huali Composed of a pile-anchor block system of common landslide blocked the decline. Because the pile anchor Rally bound to increase, thereby improving the cantilever pile of force, and can reduce the section size and placed in piles in the formation and stability of the anchorage length, it was widely used.First, from the start of slope stability, the sliding surface of a different form of landslide thrust of the calculation method for anti-slide after another - the combined effects of soil characteristics, reference, to the soil physical and mechanical parameters on the soil of the arch effect implications, as well as soil and pile spacing between the arch effect formula can be used for reference in the design, application of soil arching conclusions of the analysis, based on double pile by the deformation of the characteristics that multi-anti-slide pile design should be considered Thrust distribution, with the arch of the soil analysis, soil derived arch confrontation slippery piles before and after the transfer row thrust; papers on the next rock pile and pull anchor made a study of the interaction and access to a large number of existing literature , Summed up the pile after the thrust distribution; article went on a concrete pile anchor consideration under the coordination of deformation of single-row anchor Pile method of calculation, summed up the model.Selection of an example of the Guizhou expressway on the slope of a large-scale projects as examples of its application to simulate FLAC, that the multi-piles supporting the force characteristics, verified earlier in the theoretical exploration is reasonable. |
