摘要: 数字孪生城市为保障城市现代化建设顺利进行发挥了重要作用。本文以宁波市轨道交通第三轮建设规划为例,论证了现阶段静态、多时态的数字孪生城市能够很好地适应城市规划建设需求,阐述了数字孪生城市统一大场景建设方法。集成二维数据、地形地貌、实景三维、轨道交通信息模型、地下管线模型等多源、多尺度数据,在数字孪生城市中进行轨道交通二三维选线。贯通规划选线后,连接设计、施工和运维,轨道交通全生命周期管理在数字孪生城市中构成完美闭环。在未来的时代,数字孪生城市将加速拓展其他应用,具有广阔前景。

Abstract: Digital twin city has played an important role in ensuring the smooth progress of urban modernization.This paper takes the third round construction planning of Ningbo rail transit as an example,and demonstrates that the static and multi temporal digital twin city can meet the application needs of urban planning and construction.It systematically expounds the construction method of the unified big scene of the digital twin city.Digital twin city integrates multi-source and multi-scale data, such as 2D data, landform, real 3D model, rail transit information model, underground pipeline model, etc.Use digital twin city for two-dimensional and three-dimensional line selection of rail transit.Connect the design, construction, operation and maintenance after the connection planning and line selection.Rail transit life cycle management forms a perfect closed loop in digital twin city.In the future, digital twin city will accelerate their expansion to other fields and has broad prospects.

Key words: digital twin city, rail transit, life cycle management, teleconference, planning and route selection
