During the construction of deep foundation pit support, safety risks occur frequently due to the influence of multiple factors such as geological conditions, construction technology, and surrounding environment, making it one of the major hidden dangers in urban infrastructure construction. Focusing on the construction safety of deep foundation pit support as the core of the research, this paper systematically sorts out common risk types, focuses on key hidden dangers such as collapse, leakage, and foundation pit deformation, and constructs a set of risk identification and prevention and control system with strong pertinence and high operability, covering the construction preparation stage, support structure design, on-site management, and emergency response. On this basis, it puts forward prevention and control strategies such as intelligent monitoring, hierarchical management, and emergency linkage, aiming to improve the level of construction safety assurance and provide theoretical reference and practical experience for similar projects.
