In order to ensure the construction safety and quality during the excavation process of deep foundation pits in subway stations,this article introduces a subway station project as an example and plans in detail the con-tent of deformation monitoring for deep foundation pit excavation,including key indicators such as displacement of retaining structures,surrounding surface settlement,and changes in supporting axial force.Subsequently,the moni-toring implementation methods and measurement point layout strategies were elaborated,including the establishment of high-precision control networks,accurate measurement and review of monitoring initial values,and the execution of specific monitoring steps.Finally,a thorough analysis of the monitoring results was conducted,revealing the deformation patterns and potential risks.The research results indicate that through a scientifically reasonable monitoring plan,the deformation caused by deep foundation pit excavation can be effectively controlled,providing important basis for construction safety and schedule management,and verifying the effectiveness and practicality of the monitoring plan proposed in this paper.
