| BIM technology was used in construction industry to solve the prob-lem of inefficient and poor informatization of traditional construction in-dustry.BIM technology was proved priority in construction data admin-istration and simulation data management,which brought construction in-dustry a second revolution.This study applied BIM technology on moni-toring,early warning and data management of metro construction.Revit of BIM was used to study the problem about integrative display of metro construction data and construction safety.The results of this paper are as follows:The data exchange between BIM platform and numerical analysis software was studied.Management ways of BIM model data and data ex-traction were studied in Revit platform.Extracted by API port and inter-mediate format ways were studied and their advantages and disadvantages were also pointed out.This study also brought out exchange ways of data and numerical results.Data from BIM information integration platform were exchanged.Simulation results from FLAC3D were presented in BIM information integration platform.It practicability were proved by a project in this study.BIM information integration platform was used in integrative display of metro construction data.This paper brought out the ways how BIM in-formation integration platform present construction component.Data of shield segment,metro station,tunnel and geological model were presented and integrated by BIM information integration platform.The method of generating metro model is studied,and the information of subway compo-nents and construction information are saved to the BIM platform with the component family and the model as the carrier.Data of geological model were presented by BIM information integration platform.Geological mod-el was automatic generated by second development technique.Presentation of component data,construction procedure,construction and monitoring data were modular expressed.Taking the Nanning subway project as an example,the BIM model of subway station and interval tunnel is constructed,and the geological model is automatically generated based on the data of the drilling hole.The BIM model is selected and the model is transformed to be used for numerical analysis.The integration and display of the data information on the BIM platform is realized through the extension of the property panel of the component,the expansion of the function interface and the rendering per-formance.It shows that the BIM platform application effect of safety early warning and information integration in metro construction. |
