摘要
为了探究高速公路养护作业区关键安全风险,通过citespace软件梳理相关文献,识别出36个高速公路养护作业区主要安全风险,利用专家访谈法剔除相关性较高的风险,筛选出17个关键安全风险因素,采用问卷调查收集数据,运用结构方程模型及AMOS23.0软件,对208份有效问卷进行分析,并对17个风险进行验证性因素分析。结果显示,高速公路养护作业区关键安全风险排序从大到小依次为:作业人员风险、外部环境风险、管理风险、机械设备风险。
In order to explore the key safety risks of highway maintenance operation area,36 main safety risks of highway maintenance operation area were identified by combing related literature through citespace software,17 key safety risk factors were screened out by using expert interview method to eliminate the risks with high correlation,data were collected by using questionnaire survey,and using structural equation model and AMOS23.0 software,208 valid questionnaires were analyzed,and the 17 risks were analyzed by validating factors.The results showed that the key risks of highway maintenance operation area safety were ranked from largest to smallest:operator risk,external environment risk,management risk,and mechanical equipment risk.
