Analysis Of Stress And Deformation Characteristics Of The Slope And Anti-slide Pile

Due to the complex terrain, diverse geological conditions, in the road, railway andother engineering fields, we have to face a lot of roadbed、slope and related issues,which we faced most is the actual problems of slope stability and treatment project.○1. In the design phase on slope problems, generally take geological exploration tounderstand the basic situation of the slope, and then analyze slope stability based on thetheory of strength, set the anti-slide pile by calculating to control the slope. But aftersetting pile, in practical engineering, the slope stability may change constantly due to avariety of factors, even may be instability again. Therefore we should monitor the slopeto evaluate the stability, but strength theory doesn’t consider the deformation, thedeformation data obtained by monitoring can’t analyze the stability by strength theory,so it can use the deformation theory, but the use of deformation data to evaluate theslope stability are not mature, it can’t be used, so this paper will take studies on thisaspect.○2Due to that the slope shape, retaining structure types are very complex, takingthe universality problem into account, so this paper only take high soil slope reinforcedby anti-slide pile for example, under the different parameters to simulate slope, analyzethe relation between deformation and slope stability, put forward a method onmonitoring deformation of pile to assess slope stability in project.In this paper, we choose the typical high soil slope as the research object, The mainresearch contents are as follows：1）On the basis of practical engineering, using PLAXIS finite element software, byusing the PHI-C reduction calculation method of the software to analyze the high soilslope reinforced by anti-slide pile.2）Using numerical simulation method to analyze stress and the deformation ofanti-slide pile.3）Considering changes of the slope height, internal friction angle and cohesionparameters respectively, take simulation analysis of the model under these parameters,to get the deformation of anti-slide pile and safety coefficient and other related datas, onthe basis of it, take research on the relationship between deformation of anti-slide pileand slope stability.4）Under the creep model, to analyze different models of the slope height, internal friction angle, cohesion of, to get the deformation of anti-slide pile and safetycoefficient and other related datas, on the basis of it, take research on the relationshipbetween deformation of anti-slide pile and slope stability; Comparatively analyze thedeformation of slope and pile between elastic-plastic model and creep model inPLAXIS.The main results of this study will provide a method to the slope stability analysisand put forward a method on monitoring deformation of pile to assess slope stability inproject.
