The soil nailing wall support structure for deep foundation pits is widely used in modern construction engineering. Its deformation monitoring and stability analysis are of great significance for ensuring construction safety and project quality. This paper focuses on the deformation characteristics of the soil nailing wall in deep foundation pits. Combined with engineering cases, it systematically discusses the stress mechanism and deformation laws of the soil nailing wall at different construction stages. Through the collection and analysis of on-site monitoring data, the displacement change trend of the support structure during the excavation process is evaluated, and numerical simulation methods are used to predict and verify the overall stability of the soil nailing wall. A scientific and reasonable deformation monitoring scheme can effectively grasp the dynamic response of the support structure, provide a basis for timely adjustment of construction parameters, and thus improve the safety and reliability of the support system.
