Abstract: As an effective means of detecting geological structure, geophysical techniques can provide abundant data. 3D visualization modeling can transform geophysical data into useful geological information, which is of great significance for the vivid, intuitive and accurate understanding of underground geological phenomena and structures. To meet the demand of deep 3D geological structure exploration in Xiong'an New Area, based on comprehensive geophysical data,such as borehole data, geological profiles, seismic data, logging data and so on, 3D geological structure models and shallow 3D physical models of Rongdong area are established by the technologies of 3D tectonic modeling, property simulation and mesh analysis of 3D data. The visualization and analysis of 3D models are ultimately realized, which can provide technical supports for the identification of the stratigraphic structure and tectonic framework, and the evaluation of the water sources, deep geothermal resources and construction sites in Xiong'an New Area.
