Along the Sichuan-Tibet Highway , the largest complex in nature and representative 1 to # landslide carried out in-depth research and analysis of engineering geological conditions of the landslide occurred before and after the development and changes in the law and governance conditions of stability , governance works mainly slope feet and scour protection retaining wall , drainage measures , prestressed Anchor framework , the ordinary anti-slide pile and prestressed anchor cable stabilizing piles and reliable landslide displacement , landslide thrust force monitoring data , anti-slide pile with the data validation governance project the results of theoretical calculations of correctness . Slip through confrontation branch block structures , analysis of the ordinary piles , prestressed anchor cable anti-slide pile some defects in design theory , calculation methods , with the analysis of the measured data that in the design of prestressed anchored pile should take full account of the prestressed anchor rope impact the pile Houtu body , and Morgenstern - Price law landslide thrust calculation , divided into two working conditions improved method of anchored pile design . The introduction of the concept of anchor cable tension coefficient m , is the anchor tension level contribute between piles landslide within the range of the ratio of the horizontal thrust should be pointed out that applied to the pile prestressed anchors in landslide thrust match , when 0.15 ≤ m ≤ 0.25 , the force of the pile and anchor coordination, but also more economical in the design process to a given the anchor tension coefficient value of m Inverse number of anchor cable root n . Prestressed anchor anti-slide pile engineering difficult problems , such as the loss of prestressed anchor rope strand anti-corrosion , grouting the full extent of the aquifer Anchor Construction , pointed out that the impact of factors and possible the harm , and propose a solution to the problem .
