With the continuous development of China’s economy,people’s demand for travel is increasing,and the number of bridge construction is bound to surge in the future.However,the bridge construction has the characteristics of large investment,long cycle and complex management.Therefore,it is necessary to carry out information management for bridge construction and assist bridge construction.This paper,based on BIM+GIS,combined with the characteristics and requirements of bridge construction,developed a bridge construction management system.This study realized the integration of BIM and GIS by transforming BIM model into GIS data source.The system uses VS2013 as the development environment,C# as the development language,SQL Server2012 for data management,and system development through SuperMap Objects.NET GIS components.The system consists of 7 main functional modules and 36 main interfaces.The management of the basic information,quality,schedule,cost and report of the project is realized,and the construction visualization and the three-dimensional analysis can be realized at the same time.The system uses the data of a bridge project in the reconstruction project of the Handan border to the southern section of Ma Tau in Highway G107 as the basic data.The spatial data includes 294 model data and 38 857 terrain data.The attribute data includes 585 basic data,1 034 quality information data,3 096 cost information data,and 834 progress information data.At the same time,the method of earning value analysis is introduced into the system to control the construction progress.The effectiveness of the system is verified by an example analysis. |
