市域级三维地质建模关键技术及应用
Key technologies and applications of city-level 3D geological modeling
摘要
Abstract
High-resolution 3D geological models have been used in cities to build and use an underground space.Due to the complex nature of the geological bodies and multi-source heterogeneous nature of geologic data,problem of accurate,scale,and updating of city-level modeling remains challenging.In this paper,we study key technologies of city-level geological modeling,such as multi-segment fusion,accurate geoscience-based geological structures characterization,seamless model integration,and dynamic update.A complete workflow consisting of data preparation,structural and attribute modelling,model coupling,and test is made.Two case studies,large-scale modelling of the whole Beijing area,and detailed modeling for Nanning rail transit line,are tested.Issues of low data quality,low capability of representing complex geosciences,and poor platform integration and interaction remain.Geological modeling technology is now advancing toward higher intelligence,platform unification,and more sharing and interoperability.关键词
