Numerical Analysis Of Pile-Anchor Support System In Foundation Pit

When it talks about the building foundation of urban construction projects, it is necessary to ensure the security and stability of the foundation,and it also need to ensure it does not have the frustrating effect to the environment. Traditional strength-based control design methods have been gradually replaced by deformation control theory.Because of the influence of the underground pipeline which have a wide distribution around the project as well as the limitation about working surface,Pile-Anchor support system is often used in engineering.In view of the features of deep foundation, this article summarizes the impact when the supproting piles added supports,and describes the current design methods and theories on Pile-Anchor support system.Foundation pit is a spatial structure with the length,width and depth.In the general design and research, it is often simplified as a two–dimensional plane strain analysis of the issue. However, it is not a complete reflection of the found ation spatial properties as well as the size effect of space characters. Therefore, it is necessary to analyse with three-dimensional method.During the pit method, the finite element method analysis has become a practical and effective means.In this paper,the finite element program ABAQUS is used to consider the interaction between the supporting piles and the earth.,and have do reaserch about the reaction of the soil body and the supporting piles in the excavation process,and has also discussed the geometry size impact to structure angle department effect, the retaining wall displacement, the earth pressure distributed influence.
