Trend Assessment of Safety Management Status of Bridge Construction

Trend assessment of safety management status described the variation of the safe state during the process of construction, and it is an early warning of safe accidents to some extent. So the study of it is becoming a burning question. Aim at the uncertainty and the dynamic characteristics of the system; the trend assessment model of bridge construction safety management status has been set up using the theory set-pair analysis and Markov chain. The application results show that this model can predict the safety management status of the next and final stage relatively accurately, and it can play a guiding role in preventing safety accidents.
