Abstract: In order to further perfect the discipline of system safety, and deeply explore the characteristics and rules of the system safety structure, based on knowledge of the safety system engineering, the system theory and safety principles, a theory of system safety structure were proposed and furmalated in this paper. Through cause analysis and study on evolution rule of safety structure for the system safety issues, concepts were defined for normal structure, strain structure and failure structure. The evolution rules of the three were analyzed. Then, a three evolutionary track structure model was built for reflecting the relationships between evolution of accident and disaster and change of system safety structure. The results show that the theory of system safety structure is a supplement to the safety analysis theory for complex system,and that this theory remedies the deficiency in the safety system science's theory concerning the relationship between system structure and system safety, and puts forward new ideas and methods for solving the safety issues of complex system.

Key words: safety system science, system safety structure, normal structure, strain structure, failure structure
