时态数据在地铁施工进度模拟中的应用OA

During the construction process,temporal data is the foundation of simulating construction progress.On the basis of three-dimensional spatial data,the time dimension is added,and the spacetime data processing of subway construction progress is carried out based on multi-dimensional temporal data,and it is directly applied to subway construction progress simulation.It can fully express the dynamics of subway construction process changing with time,and it is convenient for dynamic query and analysis of progress,which has great practical significance for guiding and managing construction in subway engineering.Firstly,the paper introduces the concept of temporal data and key technology applied in construction progress simulation.Secondly,it uses the case of the rail transit BIM data integration and project management platform to illustrate the collection,manipulation and processing of temporal data,and outline the methods for expressing changes in temporal attribute data.Finally,it utilizes three-dimensional visual technique to simulate the construction process,and research results indicate that the simulation of the temporal data model in the subway construction process is of great significance.
