摘要
结合SPA与MC方法,从组织管理因素、作业人员个体因素、环境因素、技术因素四个维度建立指标体系,构建地铁施工作业人员不安全行为风险动态评估模型。以某地铁项目为例,对16个施工时段的作业人员不安全行为风险状态进行动态评估及预测。结果表明:地铁施工作业人员不安全行为风险为“低风险”,集对势及悲观势均整体向低风险等级发展;计算了稳态联系度,表现为同势,势力较强,基本安全,有向好发展的趋势。评价模型能够科学合理地反映施工作业人员不安全行为风险状态,为地铁施工单位动态评估作业人员不安全行为风险提供了新的评价方法。
An index system was established from four dimensions,which were organizational management factors,individual factors,environmental factors and technical factors,and a dynamic evaluation model for the unsafe behavior risk of subway construction workers was built on the basis of SPA and MC.Finally,a subway project taken as an example,the risk status of unsafe behavior of operators in 16 construction periods was dynamically evaluated and predicted.The results show that the risk of unsafe behavior of subway construction workers is low and the set pair potential and pessimistic potential develop to the low risk level.The steady-state connection degree is calculated as homogeneity,strong power,basic security,and a trend of good development.The case shows that the evaluation model can reflect the risk status of unsafe behavior of construction workers scientifically and reasonably,which provides a new evaluation method for subway construction enterprises to dynamically evaluate the risk of unsafe behavior of construction workers.
