Application Study Of Anti-slide Pile In Er’mi Landslide Treatment

In this paper, combined with theoretical analysis, experiments and numerical method areemployed to study the outcomes of landslide control using piles, the interaction in pile groupsand pile design. The main contents and achievements of this article are as follows:Introduced the principle of bottom friction test of the anti-slide pile simulation method,based on slope deformation destruction and anti-slide pile of the supporting effect Landslideexperimental research. Experimental results show that the anti-slide pile method is a veryeffective pierced prevent and skid effect will be better with the increase in the number ofanti-slide pile row; double-row anti-slide pile is set row spacing should not be too large, whilelaying anti-sliding piles should be located as far as possible on resistance to slip paragraph;setting multi-shot anti-slide pile with row spacing decrease, decreases the rear stabilizing pileswithstand remaining landslide thrust.Considering the deficiency of traditional calculation methods of stabilizing force, firsttime, this method is applied to the double anti-slide pile design calculationsi in this paper.This method was then verified in an engineering example.Slope engineering of the Jilin-Yanji highway Dunyan extension, a practical case, theapplication of the finite element analysis software for the numerical simulation analysis.Results show: the safety factor obtained by finite element method is similar with imbalancethrust force method. Though the distributions of sheers are slightly different.This paper combines the theoretical analysis and engineering application of anti-slide pile,using the laboratory test results as the theoretical guidance, the indoor research to guideengineering application, it has important practical value and theoretical significance.
