Stress Analysis And Application Of New H Anti-slide Pile

Landslide is an extremely serious geological disaster.Once a disaster occurs,it will affect the lives of these people and cause huge property losses.Therefore,in order to avoid disasters and reduce loss of life and property,landslide control has become an iMPortant issue in our engineering construction.In order to control the landslide disaster reasonably and effectively,this paper takes the new h-type anti-slide pile as the research object,and discusses the deformation state of the landslide in the landslide of the new h-type anti-slide pile.Because the new h-type anti-slide pile belongs to a new type of anti-slide retaining structure,the theoretical research on the new h-type anti-slide pile is extremely rare,so this has led to the application of the new h-type anti-slide pile in practical engineering.Theoretical guidance,a lot of data is often based on experience,and can not meet the engineering needs very well.In order to solve this problem,according to the force characteristics and engineering characteristics of the new h-type anti-slide pile,the mechanical mechanism of the new h-type anti-slide pile is studied by combining theoretical analysis and numerical simulation.The main contents and results of the research of the thesis are as follows:(1)The distribution form of the landslide thrust of the new h-type anti-slide pile is analyzed systematically,and the mechanical model of the new h-type anti-slide pile is established according to the distribution form of the landslide thrust.Then based on the knowledge of structural mechanics,the mechanical model of the new h-type anti-slide pile is theoretically deduced,and the theoretical calculation method of the new h-type anti-slide pile is proposed.(2)Using ANSYS finite element software to analyze the deformation of the landslide under natural conditions and the new h-type anti-slide pile.It is concluded that under these two conditions,the stress strain and displacement of the new h-type anti-slide pile are affected by the landslide thrust.(3)The internal force calculation of the new h anti-slide pile was carried out by numerical simulation.The displacement,shear force and bending moment of the new h-type anti-slide pile under the action of the tie beam and the cross bracing were analyzed.The distribution form and variation law of the bending moment of the new h-type anti-slide pile are obtained.(4)Using numerical simulation,the influence of new h-type anti-slide piles on the stress state of the front and rear piles of the new h-type anti-slide piles under different anchoring depths,different lengths of connecting beams and different lengths of row spacing are analyzed.And the displacement variation of the new h-type anti-slide pile.
