Through systematic identification of construction risk factors under complex urban conditions, a refined risk engineering checklist is compiled, a customized monitoring system is designed, a risk identification‑assessment‑early warning framework is established with operable emergency plans, standardized monitoring operation procedures are formulated, and dynamic optimization of the monitoring scheme is achieved. The research develops a set of monitoring technical systems adaptable to complex urban environments, providing a practical and feasible technical solution and engineering practice reference for subway tunnel construction monitoring under such conditions.Complex urban environment, Subway tunnel construction, Construction monitoring, Monitoring system design
