BIM技术在建筑施工现场危险源管理中的应用研究

Research on Hazard Management of Construction Site Based on BIM Technology

为保证建筑施工现场施工安全,有效防止施工事故的发生,基于BIM、GPS/GIS、无线传感技术WSN(wireless sensor networks)、激光扫描LST(laser scanner technology)等技术,构建了建筑施工过程中的危险源管理系统框架,重点分析了该系统中的关键环节,包括数据采集层、数据处理层、模型应用层、可视化展示层,并对该系统的功能和数据逻辑进行了详细分析。该危险源管理系统以集成化的BIM安全信息模型为基础,通过现场安装的各类传感器等实现对现场数据的实时采集,实现BIM模型与现场工作环境进行实时交互,再通过基于Revit的二次开发,将整合好的直观危险源数据库与三维BIM模型进行对接,实现基于可视化三维模型平台实时环境下危险源的识别,实现对建筑施工过程危险源的实时动态管理。

In order to ensure the safety of construction site and prevent the occurence of accident during construction, the paper constructs the hazard management system framework based on BIM , GPS/GIS, WSN and LST technology. The key links are analyzed mainly, including data acquisition layer, data access, model application layer and visual presentation layer. At the same time, the function and data logic of the system is analyzed. The hazard management system is based on the integrated BIM safety information model. Through the sensors on the site that acquire the real-time data, the system can realize data real-time interaction. And through the secondary development based on Revit, the system can dock the hazard data base and BIM model, which can distinguish the real-time hazard based on visualized 3D model and effectively and dynamically manage the hazard on the site.
