摘　　要：为预防施工安全事故,利用建筑信息模型(BIM)和定位技术(PT),研究工人不安全行为的预警机制。通过对施工现场工人不安全行为的统计分析,探讨工人不安全行为的分类,包括接近危险源、安全用品使用不当、违章操作,分析安全事故预警的信息需求,如工人及机械设备位置信息、工人属性及装备信息、工人及机械设备动作信息等,进而构建集成BIM和PT的工人不安全行为预警系统,划分现场不安全区域、工人属性和预警级别,分析系统功能。研究表明,该系统可通过对工人位置信息和行为信息的获取、处理和反馈,实现现场事故的预防(如坠落、碰撞等),从而提高施工现场安全管理水平。In order to prevent construction accidents on site, the warning mechanism for on-site workers unsafe behavior was studied by using BIM and PT. Kinds of unsafe behavior of workers on site were analyzed and classified, including approaching dangerous areas, misusing personal protective equipment and violating operating regulations. The demand of information for accident warning also analyzed, e.g. location, properties and actions. Furthermore, a BIM-PT-integrated warning system was developed and its initial settings （ e. g. unsafe areas, workers properties, warning levels） and functions also presented. With the information on workers location and actions, this warning system can identify workers unsafe status （e. g. falling from height, collision, etc. ）, automatically send warning messages to relevant workers and managers, and therefore improve the levet of safety management on site.
