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 NK
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.
