Deep foundation pit engineering is widely used in urban construction, and the safety of its supporting structure is directly related to the surrounding environment and construction safety. According to the deformation characteristics of deep foundation pit supporting structure in the process of excavation, combined with monitoring data analysis and early warning technology, the possible instability risk is dynamically evaluated. Through real-time collection of multi-dimensional data such as support structure displacement, surface settlement and groundwater level, a high-precision deformation monitoring system is constructed, and an early warning model based on big data and multi parameter coupling is introduced to realize rapid identification of abnormal conditions and risk grading response. The results show that scientific and reasonable monitoring and early warning technology can significantly reduce the incidence of engineering accidents and improve the safety and controllability of deep foundation pit construction.
