城市地下空间三维建模方法及应用

Three-Dimensional Modeling Method and Application of Urban Underground Space

城市地下空间的合理开发利用对于优化国土空间布局,缓解地上城市资源和空间压力起着重要作用,随着智慧城市、数字城市的提出,城市地下空间三维建模逐渐成为当下城市治理的热点与难点问题。从地下空间数据获取方法入手,以吴中区某地下停车场为例,基于多源数据融合的三维建模方法,对当下城市地下空间三维建模研究方法及应用进行介绍和梳理。结果表明,通过各类型数据优势互补,采用基于多源数据融合的三维建模方法较好地完成了地下停车场的建模,使其能够更好地反映城市地下空间的三维结构,为建筑设计人员提供了客观完整的数据支持。

The rational development and utilization of urban underground space plays an important role in optimizing the layout of land space and relieving the pressure of urban resources and space above ground,three-dimensional modeling of urban underground space has gradually become a hot and difficult issue in urban governance.Starting with the method of acquiring underground spatial data,taking an underground parking lot in Wuzhong district as an example,the 3D modeling method based on multi-source data fusion,this paper introduces and sorts out the research methods and applications of 3D modeling of urban underground space.The results show that the three-dimensional modeling method based on multi-source data fusion can better complete the modeling of underground parking lot,which can better reflect the three-dimensional structure of urban underground space,for the architectural designers to provide an objective and complete data support.
