摘　　要：为识别导致建筑工程塔吊安全事故的关键致因和链路,提出一种基于复杂网络的塔吊安全事故致因分析方法。首先,依据塔吊安全管理法律法规、标准规范,结合文献研究成果和系统思维,将塔吊安全事故致因归纳为6个子系统和34项致因;在此基础上,以我国有关管理部门发布的194份塔吊安全事故调查报告为实证数据,以致因为节点,以致因关联为边,构建塔吊安全事故致因网络模型;计算和分析网络模型的度、强度和最短路径等统计指标,确定导致塔吊安全事故的9项关键致因、3组强关联致因和3条关键致因链路。这些关键致因和链路可以作为实践中塔吊安全管控的重点。In order to identify critical causes and paths of tower crane accidents in construction engineering,a causation analysis method was proposed based on complex network.Firstly,accident causes were classified into 6 subsystems and 34 factors based on literature review and system thinking according to relevant laws,regulations and standards about tower crane safety.Then,with empirical data of 194 tower crane accident reports from relevant department in China,an accident causation network model of tower crane was established with causes as nodes and correlations among them as edges.Finally,statistical indicators of the model,such as degree,strength and shortest path,were calculated and analyzed,and nine critical causes,three pairs of strongly related causes and three key causation paths were identified.All these causes and paths can be taken as priorities during practice of tower crane safety control.
