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.
