Pile-anchor support structure has the advantages of reasonable force form,large support stiffness,saving construction space,etc.,which is widely used in deep foundation pit support.Based on the pile-anchor support structure of a foundation pit in Dingxi City,the paper calculates and ana-lyzes the influence of the maximum internal force and displacement of the pile body under different prestressed anchor cable combinations,and rationally selects the parameters of the pile body and an-chor cable.It can effectively reduce the internal force of the pile body and the displacement of the pile top,making the force of the pile structure more reasonable,and obtain a more reliable and eco-nomic support scheme.
