The factors affecting urban rail tunnel construction projects are very complex and are influenced by many factors such as the social environment, the construction process, and the way construction is managed. These influencing factors interact with each other, leading to the complexity of the development risks of this type of project. However, at present, the research on engineering construction risk is mainly focused on the field of housing construction, and there are few researches on the risk of urban tunnel construction. At the same time, with the continuous development of urbanization, the coverage of urban underground rail transport is increasing, so it is of great theoretical and practical significance to study the construction process of urban underground tunnels. This paper uses the literature collection method and the LDA model to initially identify the impact factors, and on this basis, the final set of evaluation impact factors is determined by means of expert interviews. Based on the set of influencing factors, the Dematel-ISM model was used to obtain a comprehensive analysis of the factors affecting urban rail tunnel construction projects by comparing topological maps and obtaining a Dematel-ISM model diagram with a cause-effect reachable hierarchy. Finally, the results obtained are applied to the actual development to verify the validity of the model. The results of the study show that construction operation, sequence arrangement, and procedure selection are the key influencing factors for safety risks in urban rail tunnel construction projects.
影响城市轨道隧道施工项目的因素非常复杂，受到社会环境、施工过程和施工管理方式等诸多因素的影响。这些影响因素相互作用，导致该类项目的发展风险具有复杂性。然而，目前工程建设风险的研究主要集中在住房建设领域，对城市隧道建设风险的研究较少。同时，随着城市化的不断发展，城市地下轨道运输的覆盖面不断扩大，因此研究城市地下隧道的施工过程具有重要的理论和实践意义。本文采用文献收集法和 LDA 模型初步识别影响因素，在此基础上，通过专家访谈确定最终的评价影响因素集。基于所确定的影响因素集，采用 DEMATEL-ISM 模型通过拓扑图比较，获得城市轨道隧道施工项目影响因素的综合分析，并获取具有因果可达层次结构的 DEMATEL-ISM 模型图。最后，将得到的结果应用于实际发展中，验证模型的有效性。研究结果表明，施工操作、顺序安排和程序选择是城市轨道隧道施工项目安全风险的关键影响因素。
