| 摘 要： | 为统一雄安新区地层序列划分标准，实现雄安新区工程勘察数据的入库、互相调用和综合利用分析，在搜集雄安新区大量工程勘察资料的基础上，综合考虑地质年代、地质成因、沉积序列、地层岩性、物理力学性质等因素，对雄安新区100 m深度范围内的地层进行了统一划分，并对标准地层采用"主层编码+岩性亚层编码+特殊成分编码+工程性质次亚层编码"的形式进行了标准化编码。将雄安新区100 m以浅地层自上而下划分为18个主层，其中冲洪积层及冲湖积层、5个钙质结核层是具有典型特征的标志层，可作为地层划分的重要依据，并根据颗粒粗细对各主层内的亚层进行了分层。雄安新区100 m深度范围内地层序列划分标准的建立，可为勘察单位在雄安新区规范、标准地开展工程地质工作提供借鉴，同时也可满足政府部门对工程地质数据的有效管理与精准服务的需求。

| Abstract: | In order to unify the stratigraphic sequence division standard, realize the warehousing, mutual transfer and comprehensive utilization analysis of the engineering survey data of Xiong'an New Area, the paper has uniformly divided the strata within 100 m depth of Xiong'an New Area on the basis of collecting a large number of engineering survey data and comprehensively considering the geological age, geological origin, sedimentary sequence, formation lithology, physical and mechanical properties and other factors.The standard stratum is standardized in the form of "main layer code + lithologic sub layer code + special component code + engineering sub sub layer code".The shallow stratum 100 m above Xiong'an New Area is divided into 18 main layers from top to bottom, of which the alluvial diluvium, alluvial lacustrine deposit and five calcareous nodule layers are typical marker layers, and the sub layers in each main layer are layered according to the particle size.The establishment of stratum division standards within 100 m depth of Xiong'an New Area can provide reference for the exploration units to carry out engineering geological work in Xiong'an New Area in a standardized and standard manner, and can also meet the needs of government departments to achieve effective management and accurate service of engineering geological data. |
