摘要: 为预防和减少建筑施工安全事故,研究其事故致因。首先,以系统思维和事故致因理论为基础,建立一个结构化的施工安全事故致因系统模型,包含6个子系统、16个因素和39个子因素;然后,查阅2005—2017年间我国发生的812起施工安全事故的调查报告,统计报告中39个子因素出现的频率,依据频率大小将事故致因划分为关键、重要、次要和一般等4个级别;最后,以2016年江西丰城电厂冷却塔坍塌事故为例进行实证分析,验证模型的有效性。结果表明:作业人员违规作业、安全检查不充分和管理人员履职不充分为建筑施工安全事故的3个关键致因,应高度重视并重点管控。

Abstract: In order to prevent and reduce construction accidents, a method combining accidents statistical analysis and the typical accident analysis was put forward to find out the critical causes of construction accidents. Firstly, a construction accident causation system model was built based on system thinking and accident causation theory, which contains six subsystems, 16 factors, and 39 sub-factors. Then the investigation reports of 812 accident cases from 2005 to 2017 in China were collected and causes of them were analyzed and counted. According to that, 39 sub-factors of accident causes were divided into four severity levels: critical, important, secondary, and normal. Finally, a collapse accident of Fengcheng power plant project in Jiangxi Province in 2016 was used as a case study to verify the effectiveness of the model. The results show that workers' wrong actions, inadequate safety inspection and safety engineer's mismanagement are three critical causes of construction accidents, which should be paid more attentions to and controlled.
