To propose effective safety cognition strategies and reduce safety accident occurrence，it is urgent to investigate the safety cognition evolution process and characteristics of cavern constructors. Firstly，factors affecting safety cognition were identified based on a complex sociotechnical system and the 24Model，then a safety cognition index system of cavern constructors was proposed. Subsequently，the weight coefficient was calculated by the Super Decisions software. Then，system dynamic (SD) theory was used to determine the interrelationship between factors. SD numerical model was developed including organizational safety management and other three subsystems，and a cognitive correction mechanism based on safety investments was applied to the SD numerical model. Finally，numerical simulations and sensitive analysis were performed by the SD model based on actual engineering examples. The results indicated that the overall safety cognition of cavern constructors changed from a downward trend to an upward trend by increasing safety investments and exerting the role of cognitive correction mechanisms with project processes. Organizational safety management has the greatest influence on the safety cognition of carve constructors，which was consistent with the assumption of 24Model. Therefore，the scientific performance of the SD numerical model was validated.
