Research on Deformation Observation Scheme and Structure of Deep Foundation Pit
In order to ensure the safety during the construction of foundation pit,this paper summarizes the deformation principles and deformation observation purpose of deep foundation pit.Taking the deep foundation pit project of a subway tunnel as the research object,the deformation observation scheme of deep foundation pit is expounded from the aspects of measuring point arrangement,observation frequency,early warning standard and abnormal data processing.The variation law of horizontal displacement of supporting pile top and surrounding surface settlement with observation time is analyzed.The research results can be used as reference for similar projects.
