    摘要:

    岩土地层构成了地下空间的基本物质环境,对地下空间开发利用影响巨大,深入认识、分析岩土地层结构特征可以为地下空间的开发打下坚实基础。郑州市区主要分布粉土、粉质黏土、黏土、粉细砂、中粗砂等松散地层,局部存在软弱土、湿陷性黄土等特殊土。依据岩土地层在垂向上的组合关系,划分为单层结构、双层结构、三层结构和多层结构。首次按照浅层(0~-15 m)、次浅层(-15~-30 m)和次深层(-30~-50 m)对郑州市区地下空间的地层结构分别进行了论述,为地下空间开发利用提供了准确的地质资料。提出了西部新城区重点开发建设地下仓储、地下能源生产设施;主城区建设地下储水管廊和排水深邃;东部新城区连霍高速公路以北作为地下空间开发避让区;航空城区重点建设地下仓储、现代物流通道等设施的地下空间开发利用建议,并探讨了地层结构对郑州市海绵城市建设、路面塌陷的影响。

    Abstract:

    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.
