Aiming at the dynamic risk identification problem in shield tunnelling, and with the lack of research on dynamic risk identification theory and human factors in shield tunnelling, an analysis model of shield tunnelling based on REASON model has been proposed to establish in this paper. Relying on the fault tree theory and the model that established, the accident rule base has been built. After forming the REASON model into a network, the dynamic risk identification model for shield tunnelling has been built to provide theoretical guidance for dynamic risk management during the construction.
