摘要
随着经济蓬勃发展与城市化快速推进,超大基坑工程的规模与数量激增,然而,超大地下空间结构施工面临着地下环境复杂、致险因素众多等挑战,其安全问题日渐显著。针对超大地下空间结构施工过程中面临的复杂问题,通过引入物联网技术和数字孪生理念,提出了一个适用于超大地下空间结构施工的智能化安全监测孪生系统,同时探究了物联网和数字孪生的融合机理。该孪生系统利用BIM技术建立对应的物理施工模型,并通过物联网技术实时采集多源异构监测数据实现虚拟施工模型与物理施工模型的信息交互,借助孪生系统对多源异构数据进行实时安全分析,得到结构的安全状态并反馈在应用服务层中,通过实例项目验证了孪生系统在超大基坑施工中的有效性和实用性。
With the rapid development of economy and urbanization,the scale and number of super-large excavation pit projects have surged.However,the construction of super-large underground space structure is faced with challenges such as complex underground environment and many risk factors,and its safety problems are becoming more and more obvious.Aiming at the complex problems faced in the construction process of ultralarge underground space structure,the paper proposed an intelligent safety monitoring system suitable for the construction of ultra-large underground space structure by introducing the Internet of Things technology and the concept of digital twin,and explored the integration mechanism of Internet of Things and digital twin.BIM technology was applied in the twin to establish the corresponding physical construction model,and multi-source heterogeneous monitoring data was collected in real time through the Internet of Things technology to realize the information interaction between the virtual construction model and the physical construction model.The realtime safety analysis of multi-source heterogeneous data was carried out with the help of the twin system,and the safety status of the structure was obtained and fed back to the application service layer.The effectiveness and practicability of the twin system in the construction of super-large excavation pits were verified by an example project.
