Abstract

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
