Soil Engineering Division of Geological Units Based on the Combination of Stratigraphic Age and Lithological Association for Wuhan Metropolitan Area

摘要: 第四纪地质是工程地质的基础，第四纪沉积物的地层时代、岩性组合等是土体工程地质单元划分的重要依据.通过武汉市地貌、第四纪地质特征（地层、成因、岩性等）及土体工程地质性质等综合调查和分析，提出基于"地层时代+岩性组合（岩石地层单位）+岩性层"的武汉市工程地质单元体划分原则.根据城市建设的需要，将武汉市都市发展区土体工程地质单元体分为3级：单元层（1）、亚单元层（1-1）、基本单元层（1-1-1），其划分的控制因素依次为：地层时代、岩性组合（岩石地层单位）、岩性层.据此划分出工程地质单元层6个、亚单元层14个、基本单元层28个.并对各个工程地质单元体的特征进行了分析.Abstract: Stratigraphic age, lithological association and other parameters of Quaternary sediment are important basis of soil engineering division of geological units. Based on the comprehensive survey and integrated analysis of geomorphology features, the Quaternary geological characteristics (e.g. stratigraphic sequences, strata genesis and lithological characters, etc.) and the soil engineering geological properties, the zonation principle of soil unit of Wuhan Metropolitan Area is proposed as the combination of stratigraphic age, lithological association and stratigraphic sequences. In order to meet the requirements of the city construction, soil engineering of geological units of Wuhan Metropolitan Area is divided into three levels:unit layer (1), sub-unit layer (1-1), and basic unit layer (1-1-1). And the division of control factors is stratigraphic age, lithological association (rock stratigraphic units) and stratigraphic sequences, respectively. According to the above division principle, it is proposed that soil engineering division of geological units of Wuhan Metropolitan Area could be divided into 6 unit layers, 14 sub-unit layers, and 28 basic unit layers. In addition, the characteristics of each geological unit are also analyzed, respectively.
