Abstract
In order to study the stress and deformation of pile with internal support under biased pressure,this paper,based on a comprehensive pipe corridor project in Zhejiang Province,systematically analyzed the changes of horizontal displacement around foundation pit,vertical displacement on both sides of foundation pit,axial force of internal support and internal force of anchor rod under different excavation depths.The results show that with the increase of excavation depth,the horizontal displacement increases but fluctuates to some extent,and the vertical displacement increases first and then stabilizes.With the progress of construction,the axial force of internal support decreases first and then becomes stable.The internal force of the bolt is increasing but it also fluctuates.To sum up,the scheme of pile row and internal support has good application effect,and can be popularized and applied in foundation pit engineering under complex stress conditions.关键词
