雄安新区浅地表地质—地球物理三维可视化建模
3D visualization modeling of shallow-surface geological and geophysical data in Xiong'an New Area
摘要
Abstract
The construction of three-dimensional visualization models in key urban areas is important for multidisciplinary data integra-tion and intuitive presentation of spatial stratigraphic distribution.However,existing models face limitations in integrated geological-geo-physical interpretation and concrete visualization of results.In response to this,this study established a 3D visualization model based on comprehensive geophysical data,specifically including a 3D structural model and a 3D velocity model for the Xiong'an core area down to 5 km depth.It revealed the correspondence between the 3D S-wave velocity distribution and the spatial morphology of strata,and valida-ted the structural framework of alternating uplifts and depressions.To be specific,within the depth range of 0～1 km,the lateral homoge-neity of S-wave velocity reflects the stable sedimentary characteristics of Quaternary and Neogene strata.Between 1 km and 2.2 km,the velocity zoning is unclear,primarily due to fracture development in the Jixianian geothermal reservoir,which leads to a reduction in S-wave velocity.Below 2.2 km,the significant velocity contrast between the Xushui Depression and the Rongcheng Uplift is mainly attrib-uted to lithological differences and unconformable contacts.The construction of the 3D velocity model helps overcome the limitations of sparse geological data and reveals the subsurface 3D structures in the Xiong'an core area from a physical property perspective.关键词
