Abstract:In order to effectively reduce the unsafe behavior of subway construction workers and improve the effectiveness of safety management system, this paper starts from the interest motivation of both subway construction workers and safety management personnel, constructs an evolutionary game model of unsafe behavior inspection, simulates the evolution trend of the game between the two parties by using SD model, and finally puts forward strategies to reduce unsafe behavior. The results show that the equilibrium solution of the two-party game model has no evolutionary stability, and increasing the punishment can only reduce unsafe behavior in a short time, while the frequency of repeated games fluctuates more frequently, making safety management inspection more difficult; The introduction of dynamic punishment mechanism can suppress fluctuations and achieve stable evolutionary equilibrium, but construction workers still have certain unsafe behaviors; The dynamic punishment mechanism is optimized, which can effectively restrain fluctuations and reduce unsafe behaviors, achieve the most stable state and obtain stable strategies. Without inspection, construction workers choose safe behaviors, thus reducing accidents. This study provides a certain reference for formulating effective punishment system.
