Research On Applying With Sunken Anti-slide Pile In Song J.Y Landslide Treatment

In recent years,our country has support for the development of the western region that has been continuously strengthened,the Baoji region's economy has also been developing rapidly,and the infrastructure construction is also in full swing.In the course of carrying out infrastructure construction activities,people inevitably carried out some artificial reconstructions of the mountains,which in turn triggered more and more geological disasters.Among these geological problems,landslides are relatively common.During the process of landslide treatment,anti-sliding piles are widely used as a means of strengthen support.Recently,in the management of landslides with large thicknesses of slip masses,in order to minimize the length of piles and reduce the cost of treatment,sunken anti piles have been applied.However,what is the difference in force between sunken anti piles and buried piles is still a question that is worth studying going on.This paper takes an engineering example as the Song.J.Y landslide and determines to use a method to be the strengthen support,that is sunken anti pile.So we want to find a way to research on designing the sunken anti piles.The specific content includes the following points:(1)A detailed introduction to the engineering geological conditions of the Song.J.Y landslide.Understand the landslide morphology and structural characteristics,deformation characteristics and causes of formation;(2)Through theoretical calculation and analysis,determined the magnitude of landslide thrust in the free section at the sunken anti pile above the landing surfaces and the reasonable pile length at the time of top damage.And according to the actual situation of Song J.Y landslide.Derived thrust and anti-sliding resistance distribution of anti-sliding pile post-slide;Determine the position of a reasonable resultant force point,And get the internal force of the free section embedded in the pile(3)On the basis of understanding ansys,explain the influence of the change of design points of embedded piles on the stability of landslides.Key points to discuss from the following aspects: embedded anti-slide piles,the length of the free section,pile spacing,Pile section size.And then get a conclusion that is more applicable to engineering governance.
