Prestressed anchor pile and wall is a new type of light retaining structures. In recent years, has been widely used in slope reinforcement works in the construction of roads, railways, water conservancy, with the rapid development of highway, railway, the structure used for embankment the hard shoulders retaining structural engineering application is quite extensive. Not yet a mature design calculation method, there is no clear even in the relevant manuals. From applied research using theoretical analysis and numerical calculation, prototype testing, and a variety of methods to study the anchor rope pile and wall design calculation methods, this study has important practical significance and theoretical value. Pile and wall applications combined with the study of the subject of the Mountain retaining structures and Prestressed Anchor practice, the following conclusions can be drawn: ① considering the construction conditions of dynamic design calculation method is reasonable calculation method, their condition can divided into filling conditions (denoted by A condition), anchor rope condition (denoted by B conditions). ② proposed model based on Winkler elastic foundation beam theory assumes that the finite difference method, can be calculated in layered soils, variable cross-section pile, pile set multidetector Anchor pile of internal force of circumstances. The preparation of the corresponding computer program, compared with the initial parameter method and trigonometric series, the prestressed anchor cable pile and wall design calculations are more reasonable, convenient, flexible, easy to promote the application. ③ According to the results of field testing, pile set anchor rope, anchor rope to play limit pile displacement and adjust the effect of bending moment distribution, it set the location and timing of cable tensioning Tension size of the pile and anchor related. (4) based on the field test results, pile set anchor cable to change the original earth pressure distribution and size, based on the measured bending moment and displacement by inversion analysis method to analyze the different conditions of soil pressure distribution pattern and size with the measured soil pressure The comparative analysis of the physical and mechanical model under different working conditions Prestressed Anchor Pile Wall. ⑤ summarizes the steps of pile and wall design and construction process, filling part of Anchor Construction by filling Anchor Construction sequence can be divided into three types: filling anchor, first combined fill and fill in anchor anchor . ⑥ analyzed and summarized Prestressed Anchor Pile Wall failure mode can be divided into four failure modes: the anchor and pile joints destruction, destruction of the anchor cable body pile damage and overall damage. Reference conclusions, further guidance on engineering practice through the pile internal forces and earth pressure distribution law of the the prestressed anchor pile and wall design calculation methods and the conditions for the design and construction.
