The rock—soil strata constitute the basic material environment of the underground space and have a huge impact on the development and utilization of the underground space. Therefore, in- depth understanding and analysis of the structural characteristics of the rock—soil strata can lay a solid foundation for the development of the underground space.Methods:The urban area of Zhengzhou mainly distributes loose strata such as silt, silty clay, clay, silty sand, medium—coarse sand, and some special soils such as soft soil and collapsible loess. According to the vertical combination of rock and soil strata, it is divided into single- layer structure, double- layer structure, triple - layer structure and multiple- layer structure. Then, the stratigraphic structure of the underground space in Zhengzhou urban area is discussed separately according to the shallow layer (0~-15 m), the sub- shallow layer (-15~-30 m) and the sub- deep layer (-30~-50 m).Results: The shallow (0~-15 m) underground space stratigraphic structure in Zhengzhou City is divided into 3 regions, 6 sub- regions and 25 structural sections; the sub- shallow (-15~-30 m) underground space stratigraphic structure is divided into 2 regions and 28 sub- regions; the sub- deep (-15~-30 m) underground space stratigraphic structure is divided into 2 regions and 31 sub- regions. It provides accurate geological data and technical support for the development and utilization of underground space in Zhengzhou city.Conclusions: The overall structure of the underground space in Zhengzhou is relatively simple, the cost and risk of development are low, and it has great potential for development and utilization. Overall, the western piedmont alluvial and diluvial plain area is more suitable for underground space development and utilization than the eastern Yellow River alluvial plain area.Based on the stratigraphic structure characteristics of different urban areas, the following suggestions for the development and utilization of underground space are put forward: focus on the development and construction of underground storage and underground energy production facilities in the western new urban area; build underground water storage pipe gallery and deep drainage in the main urban area; north of the Lianhuo Expressway in the eastern new urban area as an avoidance area for underground space development; the Aviation city focuses on the construction of underground storage, modern logistics channels and other facilities. And the influence of stratigraphic structure on the construction of sponge city and road collapse in Zhengzhou is discussed.
