摘要
为了深入理解不安全行为对于事故的影响,通过复杂网络探究房建工程事故行为致险链的作用机理。结合房建工程相关标准规范等,形成不安全行为列表;收集近些年房建工程事故案例,提取行为致险链,利用Pajek软件构建网络模型;分析网络的度和累计度分布,描述网络特性。结果表明,入度值和出度值高的节点分别反映事故的常见直接和间接行为原因,行为致险链网络具有无标度网络的特性。研究揭示了房建工程事故的行为致险机理,在预防事故的发生和发展上具有理论和实践意义。
To deeply understand the impact of unsafe behavior on accident,this paper explores the mechanism of behavioral risk chain for building construction accident based on complex network.Unsafe behaviors are listed from relevant safety standards.In addition,accident cases are collected and behavioral risk chains are extracted.Besides,Pajek is used to construct network model. Furthermore,degree and accumulation degree distribution are analyzed to describe the characteristics of the network.The results show that input and output high-degree nodes reflect common direct and indirect behavioral reasons of accidents,respectively. Behavioral risk chain network has scale-free properties.This research reveals the mechanism of unsafe behaviors acting on building construction accidents.It is of theoretical and practical significance to prevent construction accidents from occurring and developing.
