The time-varying
method for major engineering projects. Based on control theory of project management and continuous improvement of management performance, it was proposed to use expert assessment and the safety risk check list(SRC） for tracking and monitoring safety risk during construction. Dynamic management theory was established for safety risk management in construction，from the three aspects of dynamic monitoring operation mode, organization and procedure and standardiazation of dynamic safety risk assessment. The Wuhan Erqi Yangtze River Bridge was used as a demonstration case for the empirical study of the dynamic tracking and monitoring theory. The results show that the use of dynamic management theory and method successfully controlled the safety risks within a manageable level. No accidents higher than or equal to level general occurred during its construction.
