Abstract：Research purposes ： This paper takes a subway station construction project in Beijing subway line six as the research object. There are many collaborative，cross，parallel，multi - dimensional operations interference and negative factors in the construction of the open - cut segments，undercutting segment，cover dig segment，lining and many other multi - work and multi - disciplinary engineerings. Based on the basis data in - depth analyzed of subway construction safety and environmental management - related data and the real problems， advanced virtual reality technology， significant theory， safety and environmental dynamic optimization management techniques and other methods are integrally applied to safety and environmental management in the civil construction of subway station，and scientific and advanced virtual integrate dynamic optimization system is established for safety and environmental control technology in subway construction， and corresponding software system used on the virtual dynamic optimization management is developed. Then computer virtual three - dimensional visualization of dynamic optimal controlling is executed in the whole process of subway construction project safety and environmental issues.
Research conclusions: (1) Virtual reality technology and dynamic optimization of management theory is integrally applied for the first time. Virtualization technology is used to show a three - dimensional, real and dynamic process of metro construction management, and the full dynamic optimization methods for safety and environmental management is applied for dynamic visualization of optimal control, which is the basis for managers timely decision support and decision -making and achieves safety and environmental management from the 11 invisible" to 11 visible" . (2) The significance of FS theory and safety and environmental factors analysis is used to define the key control process of the safety and environmental protection, which not only reduces the computational workload and allows managers to focus on key control procedures of daily management and avoid the phenomenon of micromanaging and blind management. (3) With the establishment of issues library and cause and countermeasure library for a dynamic safety and environmental protection of the construction, managers can timely make decisions in dynamic management process based on above. The research results of this paper are applied in the civil engineering construction management.
