Monitoring and Analysis on Pile-anchor Supporting Structure of Deep Foundation Pit Engineering

Based on a project of deep foundation pit in Henan Province,the displacement of pile top,displacement of pile body,pile internal force,soil layer sedimentation and surrounding building sedimentation in various stages of pile-anchor supporting structure of deep foundation pit are analyzed,the reason of the displacement,the internal force and sedimentation deformation are inferred,the scientific design of foundation pit is verified,then the occurrence of major accidents of foundation pit will be avoided.
