Abstract: The process of the transmission and control of hidden dangers in subway construction is very similar to that of infectious diseases. Based on an engineering example, the characteristics of the complex system in the subway construction site are analyzed, and a simulation method using the propagation dynamics model to describe the interaction and propagation of various elements is proposed. Hazard source and hidden danger data of a section of Qingdao metro line 4 from march to August 2017 are selected as the original state, using by MATLAB R2014a simulation calculation, the densities of different elements are gotten, the process of the element changed from the hazards state to the hidden state and to the controlled state is innovated, the spread and control law of the elements are displayed, the measures are adopted the special nodes are intervened, the optimal control effect is explored.

Key words: hidden trouble, small world network, propagation dynamics, control factor
