摘　　要：为了加强装配式建筑在施工过程的安全管理,有效降低施工阶段存在的安全风险,针对人员、机械、技术、管理和环境5个方面,筛选出24个安全风险因素,运用灰色关联分析和专家打分方法建立安全风险评价指标体系,结合问卷调查数据,借助SPSS和AMOS软件建立结构方程模型(SEM)对装配式建筑施工安全风险指标进行验证性分析,并利用SEM的路径系数对各指标进行权重计算.研究结果表明:人员、机械、技术、管理、环境在装配式建筑施工阶段均具有不可忽略的影响,其中影响最大的是机械因素,其次是人员因素;及时监督管理预制构件的生产质量和构件的出厂质量以及大力培训施工人员安全意识是有效降低装配式建筑施工安全风险的关键.To strengthen the safety management of prefabricated buildings in the construction process and reduce safety risks effectively during the construction stage,24 safety risk factors were selected from 5 aspects:personnel,machinery,technology,management and environment.A safety risk assessment index system was established,applying grey relational analysis and expert scoring method,and data were collected through a questionnaire survey.The structural equation model(SEM)was established with SPSS and AMOS software,and the construction safety risk indicators of prefabricated buildings were verified and analyzed.Finally,the path coefficient of SEM was used to calculate the weight of each index.The research results show that personnel,machinery,technology,management and environment all have a significant impact on the construction stage of prefabricated buildings,of which the mechanical factor is the most influential,followed by the personnel factor.Timely supervision and management of the production quality of prefabricated components and the quality of components leaving the factory,as well as strong training on the safety awareness of construction personnel,are the key to effectively reducing the safety risk of prefabricated buildings.
