The security management of underground buildings has become increasingly important. This study aims to explore an underground building security management method based on Building Information Modeling (BIM), and propose an innovative security management strategy by integrating BIM technology with security management practices. The methods section described the process of collecting security accident data, including the organization and analysis of historical accident data, as well as the construction of a BIM security management model. By collecting historical data on construction security accidents in underground buildings, statistical methods were used to classify and trend analyze the accident data, in order to identify high-risk construction stages and common types of accidents. In addition, this study also investigated the application cases of BIM technology in underground building security management, and collected practical application data of BIM technology in risk assessment, security planning, construction monitoring, and accident prevention. The research results indicated that BIM technology exhibited significant advantages in risk assessment and monitoring. Through BIM technology, the accuracy of risk identification has significantly improved, reaching a maximum of 98.2%. In addition, as the application of BIM deepened, the emergency response time continued to decrease, with a minimum of 27 minutes. These results validate the potential of BIM technology in improving the efficiency of underground building security management.
