Abstract: Objective The construction of Shanghai city railway projects is characterized by large scale, long period, tight schedules, and high risks. Therefore, it is essential to carry out exploration and practical analysis of the emergency rescue system for these projects. Method Based on the engineering practice of Shanghai Suburban Railway Airport Link Line, a three-level support system comprising of "rescue base-emergency rescue point-construction site" is established. A layout model of mobile emergency rescue points within one-hour coverage is innovatively developed. By integrating an information-based dispatching platform for emergency rescue, a collaborative mechanism featuring "coestablishing shared resources and rapid coordinated response" is formed. Result ＆ Conclusion Compared with traditional emergency systems, the proposed emergency rescue system for Shanghai city railway projects enables a shift in risk management from "passive response" to "proactive prevention", offering a replicable emergency management model for similar projects.
