Research On Information Management Platform Of Deep Foundation Pit Engineering Based On BIM Technology

More deep excavations with complicated geological and surrounding conditions is increasing at present. Meanwhile, excavation accidents arose frequently which means higher construction risks. Based on some statistical data,the proportion about excavation accidents caused by the design and the construction of excavation was more than eighty percent. To prevent excavation accidents,the information generated during excavation construction must be comprehensive analysed,BIM technology can make the best of these information.Engineers could utilize information-construction in a new way buy using BIM.Excavations BIM model contains supporting system information and geological information,Revit and Civil3D software can be use to integrate these information-model.Revit can establish supporting system model while Civil3D can establish geological model.Excavation BIM model could be immediate updating as excavation is excavating and be load into finite element software for calculating safety factor of excavation,that’s a dynamic design process.During construction, monitoring-information should be import to monitoring-information analysis system which use many numerical method such as statistics and finite element to analyze monitoring-information. This informatization-construction method based on BIM could improve the utilization of information.On this basis, informatization-construction manage platform based on BIM technology was built.This article introduced the workflow and architecture of information-construction manage platform,optimized monitoring system through visualization technology.In practice excavation project,BIM technology supported design efforts and directed excavation construction, excellent achievements were got.
