Research and Application of Visualisation Monitoring Management of Deep Foundation Pit Based on"BIM+"
Due to many risk factors and complex structural design,the existing monitoring warning behind,the deep foundation pit construction has problems of poor information linkage and low visualization.Based on building infor-mation modeling(BIM)as the core,automatic Internet of Things(IoT)collection technology,considering multi-source information integration,it is proposed to build a Wed-end pit monitoring visualization management system of the integration of automatic collection of monitoring data,real-time early warning and risk assessment,which is a structural body is firstly established by Revit and a complex geologic body modeling is established by Civil 3D to form a model carrier of pit body information and monitoring data;Through secondary development,the format lightweight is completed to realize the cross-platform reconstruction of the 3D model by the engine;With the help of the advantages of the GIS 3D spatial information data and the IoT technology,the integration with BIM is completed by computer-assisted means to achieve the purpose of comprehensive assessment of risk of pit.The application of this monitoring and visualization management system in the oversized deep foundation pit of Beijing Municipal Ad-ministrative Center guarantees the safety of its excavation,support process and surrounding environment,and shows its feasibility and advantages,which can provide experience for the safety management of foundation pit construction.
