Abstract：In order to improve the safety of subway construction, the risk coupling mechanism and the vulnerability of subway construction system are studied. By referring to the vulnerability theory and summarizing the risk factors of subway construction safety, a system vulnerability model is established. Furthermore, the domestic subway construction accidents during the period 2008 to 2020 are collected and organized, and among the 130 accidents with complete risk factors are selected to calculate the probability of risk occurrence and risk coupling values under different coupling methods, so that the key risk coupling methods affecting the system vulnerability can be attained by the N-K model. The results show that the more risk factors in the system, the greater the probability of accident occurrence; when the personnel factors, management factors and environmental factors are fully coupled, the vulnerability of the subway construction safety system shall be greater. The study clarifies the key coupling risks of vulnerability in the system and provides a reference for the control of subway construction safety.
