Research On The Application Of Anti-slide Pile In Landslide Treatment Of National Highway214Line The Dian-zang Highway Between Nianla Mountain And Qamdo Airport

As countries in western provinces to invest more, Tibet region because of itsspecial geographical position in factors such as1025planning, countries inmore increased investment with the Midwest, Tibet is increasingly frequentexchange of goods. Transportation capacity size will directly affect the Tibetarea rapid economic health and sustainable development. National highway214line to Tibet as mainland, but also an important traffic trunk lines to thefollowing qamdo airport and Lin zhi, the only the traffic trunk lines in Lhasa.Ensure the normal operation of enumeration highway safety for the developme-nt of regional economy, strengthen qamdo national unity and strengthen national defense, has the extremely vital significance. However, geological disasters inhighway landslide time in serious influence this highway normal operations.In view of the above reasons, this paper national highway214line the dian-zang highway (Tibet boundary) to following airport in pull mountain regulationrebuilding project first contract period, from K1378section pile+100~K1378+420stability of the landslide are analyzed; Calculated the decline ofthrust; landslide Through the landslide of several treatment than choosetechnical efficiency measures, and finally puts forward some choose the treatme-nt plan to pile; To calculate the anti-slide pile by internal and external force,the size of the pile body design calculation longitudinal force sinew, stirrupand tectonic muscle configuration problems; The number of calculationdesigned and layout of pile; Min road and discuss determine suitable pavementstructure form; Again, the construction process of the pile of scientific andreasonable guidance; organize and arrange Finally, the governance of thegovernance after effect evaluation of landslide, to ensure the long-term stabilityof the slope late use.
