摘要
针对隧道施工项目信息化中遇到的多源海量异构数据利用不够直观,管理难,信息共享难等问题,对3DGIS与大数据技术进行了应用研究。通过利用3DGIS技术,搭建三维隧道施工虚拟场景,建立了统一的隧道施工空间数据库,解决了隧道施工多源异构数据的集成与管理;通过利用先进的空间大数据技术,开发了隧道施工信息化管理云平台,实现了对三维海量异构数据的分布式计算、存储与共享,解决隧道施工中海量异构数据的存储与分析计算问题。平台的研发,实现了隧道施工项目中多源数据的三维一体化管理、共享与应用,并实现了对施工中的安全、质量及进度等相关数据进行管理分析,提高了隧道施工信息化管理水平。
In order to solve the problems encountered in the information management of tunnel construction projects,such as inadequate intuitive use of multi-source and massive heterogeneous data,difficult management and difficult information sharing,this paper studies the application of 3 D GIS and large data technology.By using the technology of 3 D GIS,the virtual scene of three-dimensional tunnel construction is built,and a unified spatial database of tunnel construction is established,which solves the integration and management of multi-source heterogeneous data in tunnel construction.By utilizing advanced large spatial data technology,a cloud platform for information management of tunnel construction is developed,which realizes the distributed calculation,storage and sharing of three-dimensional massive heterogeneous data,and solves the storage,analysis and calculation problems of massive heterogeneous data in tunnel construction.The research and development of the platform realizes the three-dimensional integrated management,sharing and application of multi-source data in the tunnel construction project,and realizes the management and analysis of the safety,quality and progress data in the construction,so as to improve the information management level of tunnel construction.
