摘要:

城市地下空间开发利用是智慧城市发展的重要组成部分。构建城市地下空间三维地质模型和属性模型,能够立体直观地展示地下构筑物、河道、水系等,进一步与三维模型融合后,可以更好地展示地下空间资源质量。本文以上海市中心城区地下空间资源评价为示范,设计了三维地质结构和属性模型一体化建模方法,构建了上海市中心城区地下空间三维地质模型,实现了三维地质模型与地下构筑物模型的自动融合。最后根据上海市城市地下空间资源开发利用适宜性评价模型,实现了城市地下空间资源评价的三维建模。本文成果已经应用于上海市中心城区地下空间总体规划、局部规划以及工程建设项目中。

Abstract:

The development and utilization of urban underground space is an important part of smart city development in China. The 3D geological structural and property models of urban underground space can reveal the underground structures, river channels, water systems, etc.; by integrating with 3D models, they can better show the quality of underground space resources. In this paper, taking the underground space resources evaluation in the Central District of Shanghai as an example, we designed and established the integrated method for 3D modeling of geological structure and property, constructed the 3D geological model of underground space in the Central District of Shanghai, and realized the automatic fusion of 3D geological model and underground structure model. Finally, according to the suitability evaluation model for the development and utilization of urban underground space resources in Shanghai, we constructed the 3D evaluation model for urban underground space resources. The results of this paper have been applied to the overall and localized planning and engineering construction projects of underground space in the Central District of Shanghai.

Key words: 3D geology modeling, underground space, resources assessment, smart city
