中文摘要：

为提升建筑施工安全管理水平,基于不安全行为的重要性,通过文献分析和专家访谈方式确定不安全行为集合,构建诸不安全行为间关系概念模型。根据14份调研数据,运用社会网络分析（SNA）方法构建诸不安全行为间关系网络模型,研究其结构特征、节点属性、影响力及聚类等级情况。结果表明：关键不安全行为节点可构成行为连锁反应链,并由桥节点连接成不安全行为网络,且网络具有较高风险性。其中,关键不安全行为包括安全生产管理机构设置不合理、安全检查监督体系设计不合理等;存在一些行为连锁反应链,包括＂安全生产管理机构设置不合理-施工现场指挥监督失误-作业处于不安全位置＂等;不安全行为网络的桥节点包括安全生产管理机构设置不合理等。

英文摘要：

Based on the importance of unsafe construction behavior,the set of unsafe behavior was determined and a conceptual model was built for relationship among unsafe construction behavior through literature analysis and expert interview to enhance the management of construction safety. Based on 14 pieces of investigation data,a network model of relationship among unsafe construction behavior was built by applying SNA and its structural feature,node attribute,influence and hierarchical clustering were investigated. The results show that key nodes of unsafe behavior can make up behavior reaction chains,and bridge nodes can be linked to form an unsafe behavior network which has a high risk,that the key kinds of key unsafe behavior are the irrational setup of work safety management institution and the improper design of safety inspection supervision system,that behavior reaction chains exist,including the irrational setup of production safety management institution led to errors in supervision and direction on condition,and that some kinds of behavior such as the irrational setup of production safety management institution can serve as a bridge node.
