摘要
在BIM三维空间数据的基础上加入GIS地理坐标体系以及时间维度,基于多维时态数据对地铁施工中的安全风险进行管理管控,便于安全风险的动态查询与分析。文章首先介绍了风险分级的概念以及安全风险管理应用的关键技术,阐述了安全风险相关数据的采集、操作和处理过程。围绕地铁建设,以BIM-GIS系统为支撑,以风险数据动态应用为核心,进行基于BIM-GIS的风险管理应用的建设,利用施工过程中监测、巡视发现的安全风险数据完成风险数据的填报,最后利用三维可视化技术对安全风险进行了模拟展示,研究结果表明,基于BIM-GIS的安全风险识别系统可以极大提高地铁施工过程中风险管理的效率和水平。
Based on BIM three-dimensional spatial data,GIS geographic coordinate system and time dimension are added to manage and control security risks during subway construction based on multidimensional temporal data,facilitating dynamic query and analysis of security risks.Firstly,this paper introduces the concept of risk classification and key technologies applied in security risk management,expounds the collection,operation,and processing process of security risk related data.Centering on subway construction,with the BIM-GIS system as the support and dynamic application of risk data as the core,the construction of risk management applications based on BIM-GIS is carried out.The filling of risk data is completed by using the security risk data found during monitoring and inspection during the construction process.Finally,the security risk is simulated and displayed by using three-dimensional visualization technology.The research results show that the security risk identification system based on BIM-GIS can greatly improve the efficiency and level of risk management in the subway construction process.
