Whole Life Cycle Manamagement Research In Information Of Railway Engineering Constrution Based By BIM

with the China high-speed railway construction In recent years,which has achieved remarkable results, as the "Twelve five", our country will be basically completed four vertical and four horizontal frame for high-speed rail network, the total mileage of more than 19 thousand kilometers. Railway engineering construction plays an increasingly important role in the process of modernization in our country. It plays a more and more important role in the development of railway engineering construction. It is a very important way to realize the modernization of railway engineering construction. Railway engineering construction master key assets source data, railway engineering construction information decentralized construction mode leads to the railway engineering construction industry data showing fragmentation, the lack of integration of information resources, limited resource investment, short construction cycle, repeated application construction work, it is difficult to meet the diverse needs of the railway engineering construction information applications.Therefore, the establishment of the railway engineering construction based on BIM technology of the whole life cycle management theory system and the development of integrated railway project management platform, has become an important research direction and development trend of improving railway construction management information level.Firstly, this paper summarizes the development and research status of BIM and engineering construction, and points out the development direction of the railway construction management. Secondly, based on the theory of full life cycle management (BIM), the paper puts forward the concept of life cycle management of railway engineering construction information. Finally, based on the analysis of the information needs of railway engineering construction based on BIM, the design principle of railway engineering construction information platform is put forward, and the advanced technology of cloud computing, Internet of things, big data and so on. At the same time, this paper analyzes the application of the railway engineering construction information platform based on BIM technology in Shigu mountain tunnel. And Jiangyou Subgrade.
