摘要
坍塌是建筑施工过程中常见的安全事故之一。为了有效预防坍塌事故,选取2012~2019年国内226例建筑施工坍塌事故调查报告,建立坍塌事故变量集,使用CART分类回归树算法对变量数据进行分析,生成分类树,提取得到3个坍塌事故工作特征。使用IDEF0方法构建工作特征决策链并可视化,通过分析决策链找出每个工作特征的关键制约因素和最佳风险控制点。结果表明,在建筑施工活动准备阶段进行干预决策能产生更大安全效益,且工程控制手段更有效,可为建筑施工坍塌事故重点防控提供参考。
Collapse is one of the common safety accidents during building construction.In order to effectively prevent collapseaccidents,this paper selects 226 domestic construction collapse accident investigation reports from 2012 to 2019,establishes a set ofcollapse accident variables,uses the CART classification regression tree algorithm to analyze the variable data,generates aclassification tree,and extracts 3 collapse accidents Work features.Then,this paper uses the IDEF0 method to construct and visualizethe work feature decision chain.In this way,the key constraints and the best risk control points for each work feature by analyzingthe decision chain are found out.The results show that intervention and decision-making in the preparation stage of constructionactivities can generate greater safety benefits,and the engineering control methods are more effective.This paper provides areference for the key prevention and control of building construction collapse accidents.
