郑州城市地下空间开发敏感地质因子的分布特征

在对郑州市的工程地质相关资料梳理的基础上,针对研究区工程地质特点,结合地下空间开发利用情况,认为研究区地下空间开发的敏感工程地质因子主要有淤泥质土、液化土、湿陷性黄土、钙核富集层。在地下空间开发过程中,为了研究工程地质敏感因子可能导致的环境地质问题,对淤泥质土、液化土、湿陷性黄土、钙核富集层的分布范围进行精确刻画,为地下空间开发利用提供地质依据。

Distribution Characteristics of Sensitive Geological Factors in Urban Underground Space of Zhengzhou

On the basis of analyzing the data related to engineering geology of Zhengzhou, it is concluded that the sensitive engineering geological factors of the underground space development in the study area are mainly silt soil, liquefied soil, collapsible loess and calcareous nodules enrichment layer according to the engineering geological characteristics of the study area and the development and utilization of underground space,. In order to study the environmental geological problems caused by sensitive engineering geological factors, the distribution range of silt soil, liquefied soil, collapsible loess and calcium nucleus enrichment layer is accurately characterized in the process of underground space development. The study can provides geological basis for the development and utilization of underground space in Zhengzhou.
