雄安新区工程地质三维结构模型数据集

The Xiong'an New Area is located in the plain to the east of the Taihang Mountains, where the shallow strata within 100 m under the earth's surface mainly consist of alluvial-proluvial and alluvial-lacustrine sand beds and clay layers, with excellent engineering geological conditions. Through engineering geological investigations, the China Geological Survey has obtained data of the strata, standard penetration and tests of more than 100 boreholes, thus forming a system of techniques and methods in the Xiong'an New Area, and establishing the engineering geological borehole database and a three-dimensional model. This will provide strong support for the future planning and construction in the Xiong'an New Area. This paper introduces data acquisition, data integration, geological data processing technology in engineering geological investigation, and explores the method using 3D visualization software to establish the 3D structure geological model, in a bid to provide reference for urban geological survey and dataset processing with the real application of a engineering geological dataset in the Xiong'an New Area.

雄安新区位于太行山东麓平原，地表以下100米范围内的浅部地层主要由冲洪积砂层、冲湖积砂层与黏土层构成，工程地质条件优良。中国地质调查局通过工程地质勘察工作，获取了百余钻孔的地层、标准贯入试验等相关数据，构建了雄安新区工程地质技术方法体系，并建成了工程地质钻孔数据库与三维模型。上述成果可为雄安新区未来的规划与建设提供有力支撑。本文介绍了工程地质勘察中的数据采集、数据整合及地质数据处理技术，并探索了利用三维可视化软件构建三维地质结构模型的方法，以期结合雄安新区工程地质数据集的实际应用，为城市地质勘察与数据集处理提供参考。
