The Stability Analysis Of Slope Stability Of Pile Soil Is Rein Forced By Pile Soil

As a kind of effective engineering measures,anti slide pile has a wide range of applications in the field of landslide,geological hazard prevention and slope reinforcement.Generally speaking,the relevant design theories rarely involve or even ignore the pile-soil interaction,leading to the actual engineering design and theory there is a big error,or even unreasonable.Therefore,this paper focuses on the distribution of anti slide pile in slope engineering pile after pile thrust and the resistance of soil before the critical pile spacing,landslide thrust and residual sliding force,soil arching effect and arch thickness calculation and stability analysis,are deeply researched,and the main contents of this study are expected to have the results are as follows:1.The distribution form of pile after pile thrust and the resistance of soil before the review and analysis,and simulated with the finite element analysis software MIDAS/GTS,results show that the distribution and magnitude of landslide thrust is not only related with the soil properties and deformation and constraint pile by also have a great relationship.2.if the thrust of the landslide is effectively transmitted to the pile,a reasonable spacing between the piles should be set to form a soil arch between the piles.The formation mechanism and failure mode analysis of soil arching effect,at the same time,according to the existing experimental data derived from the arch thickness calculation formula;application of Mohr Coulomb criterion on soil arching strength analysis,the critical pile spacing formula,and simulated by MIDAS/GTS software.The results show that is close to the theoretical value.3.theoretical analysis and finite element simulation show that the critical spacing between piles is not only related to pile diameter,cohesion and internal friction angle of rock and soil,but also to deformation modulus and Poisson's ratio of rock and soil.4.combined with the deformation theory and the pile deflection differential equation of the existing,analyzed the axial forces of the pile under various constraint conditions,results show that large pile head condition of displacement,the pile bending moment and shear force,the landslide thrust under the pile top hinged and fixed relative to the pile top free and does not rotate,the pile displacement,bending moment and shear force of the former is much smaller than the latter,so the strength of the pile under the conditions change on the top of the pile,the maximum bending moment and shear force of the lower.5.using the improved method of slope reinforcement,through calculation and analysis,found that the reasonable pile position of anti slide pile in landslide near the middle,and use this improved method of numerical simulation analysis of safety coefficient obtained and calculated using Lizheng results are basically the same,while the use of displacement MIDAS/GTS finite element software to establish the model the slope stability of the improved scheme is proved.
