Application And Study Of The Anti-sliding Piles In Reinforcement Technique Of Expressway Slope

Landslide is a common geological disaster which we usually met inour speedway project. It induce a large number of loss every year. How todeal with such thing is a serious challenge for highway builders. As for itssimple and fast construction and its good strengthening effect, anti-slidepile is a very efficient measure in the measures of landslide treatment,which is widely used all over the world.To start with, this thesis introduced some analysis methods of slopestability, discussed advantages, disadvantages and applicability ofdifferent methods. And then, it analysed the influencing factors for thestability of slope and pointed out that many factors affect it, including theinfluence of intrinsic and external factors. Followly, it analysed andintroduced the distribution laws of landslide-thrust and resistance ofsliding mass acting on anti-slide piles, transfering coefficient method andevery calculation methods of anti-slide pile internal force. At last, it usedthe transfering coefficient method and finite element method to analys the19 contract segment slope at Chang(De)-Zhang(JiaJie) expressway, putforward a concrete scheme of slope treatment basing on the analysis ofslope stability, analysed its stability after slope treatment withtwo-dimension finite element meshes. The results show that it gets a goodeffect and can completely satisfy the requirement of our engineeringconstruction after using the anti-slide pile.
