Study On The Design Of Anti-slide Pile Based On Stress Distribution

With the rapid development of social economy,the development of mountain areas tends to be more and more urbanization.Natural disasters are also increasing year by year.Landslide,debris flow and other disasters seriously threaten people’s life safety,resulting in serious economic losses.As the most commonly used effective engineering measure in landslide control,anti slide pile plays an important role in landslide control in the world and has been widely applied.When the current anti slide pile is designed,the thrust on the anti slide pile is often assumed to be the distribution of triangle,trapezoid,rectangle,and parabola.The thrust calculation often divides the slide into a strip,assuming that the bar is rigid and calculated under a certain safety factor,and the pile end of the anti slide pile is simplified as a simple assumption.It is calculated by means of branches,stranding and cantilevers,and four aspects are described according to the elastic coefficient of the fixed ends of piles.Because these four aspects are only obtained under certain assumptions,there is a certain gap with the field,and the selection of parameters is more arbitrary.The design theory and calculation method are still in the immature stage of semi empirical and semi theory,which is behind the application of engineering practice.Therefore,in the anti slide pile control project,it is difficult to meet the requirements of safety and reliability as well as to save investment.If the design is too conservative,it will lead to a waste of investment,otherwise there is a big engineering hazard.In this paper,based on a new numerical method proposed by Professor Luyingfa,based on the theory of generalized stress theory based on force boundary and equilibrium condition,a corresponding theoretical model is established against sliding piles,and the corresponding theoretical solutions of generalized stress are obtained--the theoretical solution of slope generalized stress and the solution of the generalized stress theory of anti slide pile,and the phase angle phase is studied.With the increase of slope height,the possibility of damage is increasing,and the slope stability is increasing with the slope angle decreasing,and the distribution characteristics of the pile stress of anti slide pile are discussed.The research shows that the stress of the slide body on the pile of anti slide pile includes horizontal stress,vertical stress and shear stress,and the stress distribution of the pile body is different,and the stability of the anti slide pile changes with the characteristics of the solid end rock soil.In this paper,the traditional stability calculation method and the new numerical method are used to calculate the anti slide pile of the living residential area,and the internal force of the pile body and the reinforcement are calculated by the correct software.The comparison shows that the new calculation method is also suitable for the analysis of the stability of the landslide calculation.
