为充分利用BIM、GIS技术可视化以及能够处理海量数据的特点，解决北京地铁19号线一期工程附属一体化设计管理过程中模型的展示、分类与存储等实际应用问题，以在建的北京地铁19号线一期工程附属一体化设计工程管理为例进行研究。创新性地对项目中涉及的基础数据进行分类，确定附属一体化信息化管理过程中所需的数据种类；通过开发的轨道交通BIM-GIS协同平台进行相关的功能应用研究，得出最终结论。全线各站首次使用BIM、GIS技术辅助附属一体化方案的设计，能够在设计阶段实现环境的可视化、附属一体化设计方案的比选等功能，并取得良好的效果。区别于传统的附属一体化设计过程，其优势主要体现在项目信息高度集成化、信息化以及设计沟通的高效便捷，为后续实现城市轨道交通数字化建造打下数据基础。

The BIM and GIS technologies have the advantages of visualization and massive data processing. As a result, they are used to solve the display, classification and storage of model and other practical application problems in the accessory integration design and management of Phase I project of Beijing Metro Line No.19. First, the basic data involved in the process of the project is innovatively classified, and the types of data needed in the informatized management process of accessory integration are determined. And then relevant functional application research is conducted through rail transit BIMGIS collaborative platform developed. It is for the first time, the accessory integration design based on BIM and GIS technologies is applied to stations along rail transit line, which realizes visualization of environment in design process and design scheme selection, and achieves good effect. Compared to conventional accessory integration design, the accessory integration design based on BIM and GIS technologies is highly integrated, informatized and efficient, which can provide data support for followed digital construction of urban rail transit.
