摘要：The horizontal displacement monitoring of the supporting piles plays a vital role in the safety judgment of deep foundation pit excavation and construction of main structure. In urban rail transit engineering, the monitoring of horizontal displacement of retaining pile top of deep foundation pit should be carried out according to the characteristics of the project, formulated a scientific monitoring plan, and selected a reasonable monitoring method. If necessary, the monitoring methods should be optimized and integrated, so as to get the real and effective monitoring data, which can reflect the change of the horizontal displacement of the foundation pit support structure to the greatest extent. By analyzing several common methods of deep foundation pit monitoring in current urban rail transit projects, the advantages and disadvantages of each method are summarized, and reasonable suggestions are proposed for accurate monitoring.
