Deformation Monitoring and Analysis and Result Analysis of in Excavation Engineering of Qingdao Subway in Hexi Station

The deformation monitoring plan are given and the in-situ monitoring study is demonstrated on the foundation pit deformation ,especially on the retaining piles deep horizontal displacement and steel strut axial forces of variation in this paper. Through reasonable and effective monitoring deformation of development foundation to meet the construction information requirements to achieve the purposes on safety prediction ,timely feedback , effectively construction guid.
