为研究地铁施工安全风险管理中的风险概率变化情况,对影响地铁施工安全的人为、设备、管理和环境等因素进行风险耦合分析,构建基于复杂网络的N-K模型,计算不同风险耦合情况发生的概率和风险值。结果表明,多因素风险耦合会增加事故发生的概率,主观因素(人为因素和管理因素)风险完全耦合比不完全耦合造成的风险大;主观因素与环境因素完全耦合最容易引起安全事故。
In order to study the change of risk probability in subway construction safety risk management, risk coupling analysis is made on the factors influencing the construction safety of subway, such as equipment, management and environment, the NK model based on complex network is constructed and the probability of different risk coupling is calculated And risk value. The results show that the multi-factor risk coupling will increase the probability of accidents, and the subjective factors (man-made factors and management factors) are more likely to be fully coupled than the incompletely coupled ones. The complete coupling of subjective factors with environmental factors is the most likely to cause accidents.
