摘　　要：为了研究建筑施工中有限空间作业的安全风险管理,通过DEMATEL方法识别和评估各风险因素之间的因果关系及其强度,并应用ISM方法对这些因素进行层次化处理,构建多层级的风险结构模型。结果表明,作业能量的隔离不当、有毒有害气体的存在等是直接影响有限空间安全的关键因素,而通风条件、作业人员的安全培训等中层因素对整体安全水平具有显著影响。通过研究旨在系统地提高有限空间施工的安全管理水平,保障工人的生命安全。研究也为有限空间事故风险的评估与控制提供了有效的理论依据和实践指导。To study the safety risk management of confined space operations in construction,this paper identifies and evaluates the causal relationships and strengths of various risk factors using the DEMATEL method,and applies the ISM method to hierarchically process these factors,constructing a multi-level risk structure model.The results indicate that improper isolation of operational energy and the presence of toxic and harmful gases are key factors directly affecting confined space safety,while mid-level factors such as ventilation conditions and safety training for workers significantly impact overall safety levels.This research aims to systematically improve safety management in confined space construction and ensure worker safety.It also provides effective theoretical basis and practical guidance for the assessment and control of safety risks in confined spaces.
