Analysis of deformation and stability impact of anti-skid pile support system on deep and high fill slopes
To study the deformation and stability effects of anti slip pile support system on deep and high fill slopes,based on a high-volt-age power tower slope project in Fuzhou,the overall stability of the slope,the internal force and deformation of the anti slip pile were studied using limit equilibrium method,finite element analysis method,etc.The stability changes of the slope,the internal force and deformation of the anti slip pile under different rainfall infiltration depths and slope top load conditions were analyzed.The results show that as the depth of rainfall infiltration increases,the horizontal deformation,axial force,bending moment,and shear force of the anti slip pile all increase,while the overall stability of the slope decreases.The influence of rainfall conditions on slope stability and anti slip piles cannot be ignored,and should be carefully considered in design.As the load on the top of the slope increases,the horizontal deformation,axial force,bending mo-ment,shear force,and overall stability of the anti-skid pile do not change much,but the adverse effects of overloading on the local stability of the slope top should be considered.
