摘要: 为提高地铁建设施工的安全性和稳定性,开展地铁工程系统抵抗风险并快速恢复能力的研究。通过引入韧性概念,分析影响地铁工程系统韧性的主要因素,利用贝叶斯网络(BN)建立表达各因素间因果关系的韧性模型,并通过调查采集的数据样本学习网络模型的参数;通过调整网络中的各结点分析各因素与系统韧性的关系,明确应采取的措施和重点控制的对象,从而提高系统韧性,确保正常施工安全有序地开展。研究表明:用该模型能够量化地铁工程系统韧性值,并推理分析各因素对韧性值的影响,从而提高建造管理能力。

Abstract: To improve the safety and stability of metro construction projects, and to ensure efficient construction activities, this paper was aimed at studying and evaluating the capability of the metro engineering system to resist and adapt to risks, as well as to maintain normal productions. A concept of resilience of metro engineering system was introduced. Factors influencing the resilience were analyzed. BN was employed for studying the ability of the metro engineering system in resisting risks and quickly recovering. A resilience model representing the causal relationships between those components has been built with a BN. Then, data samples from survey results were exploited to learn the parameters of the network, before the network can be adjusted to quantitatively analyze the impacts of the components on the system resilience, so that important actions and objects to monitor were recommended. The results show that the resilience model of the metro engineering system can be used to accurately quantify the resilience of the metro engineering system, analyze effects of the factors on the resilience, and thus improve the construction management capability.

Key words: metro engineering system, risk, resilience, Bayesian network(BN), quantitative evaluation
