摘要: 为解决多风险因素耦合作用对隧道安全施工的影响,在分析20092019年国内101次隧道施工事故发生原因的基础上,将影响隧道安全施工的风险因素区分为人为因素、设备因素、环境因素和管理因素4方面; 将风险耦合理论引入隧道施工事故风险分析中,探讨隧道施工事故多风险因素的耦合机制、分类和解耦原理,利用N-K模型构建隧道施工风险耦合模型,揭示隧道施工事故多风险因素间的耦合效应。研究结果表明: 参与耦合作用的风险因素越多,耦合作用形式计算的耦合值越大,则隧道施工风险越大。在3个风险因素参与的耦合过程中,人为-设备-环境因素之间的相互耦合作用造成的隧道施工风险最大;在2个风险因素参与的耦合过程中,设备-环境因素之间的相互耦合作用造成的隧道施工风险最大。基于解耦思想,可以减小隧道施工中各风险因素之间的耦合效应,进而降低隧道施工事故发生的可能性。

Abstract: The causes for 101 tunnel construction accidents in China between 2009 and 2019 are analyzed to resolve the coupling effect of multiple risk factors on tunnel construction safety. To this end, the risk factors affecting tunnel construction safety are divided into four aspects: human, equipment, environmental, and management factors. Subsequently, the risk coupling theory is introduced into the risk analysis of these tunnel construction accidents, and then the coupling mechanism, classification, and decoupling principle of multiple risk factors accounting for tunnel construction accidents are discussed. Moreover, the NK model is used to build a tunnel constructionrisk coupling model. Based on the NK model, the coupling effect of tunnel construction accidents among multiple risk factors is revealed. The results also show that the more risk factors involved in the coupling effect, the greater the coupling values calculated by the coupling action form, and the greater the tunnel construction risk. It is observed that the coupling effect of humanequipmentenvironment factors causes the greatest tunnel construction risk in the coupling process involving the three risk factors. However, in the coupling process involving only two risk factors, the coupling effect between the equipment and environmental factors poses the greatest risk to tunnel construction. Therefore, based on the decoupling idea, it is established that the coupling effect of various risk factors in tunnel construction can be reduced, including the possibility of further reducing tunnel construction accidents.
