摘　　要：脚手架工程是建筑工程中的一项重要的措施项目,脚手架工程中的施工风险成为建筑施工过程中的一个重点问题。本文在参考相关文献和脚手架事故实例的基础上,确定导致脚手架事故发生的影响因素,通过构建DEMATEL模型探究各影响因素之间的内在关联和作用程度,确定关键因素;运用ISM模型得出各因素间3阶6层递阶结构模型,提出具体对策和建议。结果表明:安全管理制度不完善、教育培训不充分等6项关键因素是造成脚手架事故发生的主要原因。其中,工人安全意识薄弱和施工现场管理不到位是造成脚手架事故的直接因素,安全管理制度不完善是最根本因素。本文成果可为脚手架工程施工安全提供理论参考。Scaffold project is an important measure item in construction engineering,and the construction risk in scaffold project has become a key problem in the construction process.Based on the relevant literature and scaffold accident examples,the factors influencing the occurrence of scaffold accidents are determined.By constructing the DEMATEL model,the intrinsic correlation and degree of action of various influencing factors are explored,and the key factors are determined.The ISM model is used to obtain a three-order and six-layer step-down structure model between each factor,and specific countermeasures and suggestions are proposed.The results show that six key factors,such as imperfect safety management system and insufficient education and training,are the main reasons for scaffold accidents.Among them,the weak safety awareness of workers and the inadequate management of the construction site are the direct factors causing scaffold accidents,and the imperfect safety management system is the most fundamental factor.The results can provide a theoretical reference for the construction safety of scaffold project.
