With the rapid development of urban underground infrastructure,shield machine construction has been widely used as an important method in tunnel engineering.However,various risk factors in the construction process have also increased.How to accurately assess and effectively manage these risks has become the focus of the industry.In this study,the fuzzy comprehensive evaluation method is used to systematically evaluate the risks in the construction process of shield machinery,and the corresponding management strategies are proposed.The results show that the fuzzy comprehensive evaluation method can more accurately identify and evaluate the construction risk,thus providing strong support for risk management.
