Since the development of underground space has the characteristics of “difficult to recover, one-off, and difficult to budget”, the planning of underground space is particularly important. Traditional two-dimensional planning technology is difficult to describe three-dimensional spatial information such as underground complex geological environment, and three-dimensional GIS technology can solve this problem better, which can greatly enrich the urban planning, construction, and management control methods. This paper uses a combination of GIS software to carry out the three-dimensional geological modeling of above-ground and underground integration in the study area, and puts forward application suggestions for the underground space planning of the area, providing support for decision-making support for the government and relevant departments. and provide a demonstration for other cities to carry out urban geological survey work.
