Multi-attribute 3D geological modeling for urban underground space development and utilization:A case study of the Langfang Air Economic Zone
摘要
Abstract
[Objective]With rapid urbanization,the demand for urban underground space is increasing significantly.This study addresses the challenge of insufficient characterization of subsurface geological conditions to support the scientific planning and construction of the Langfang Airport Economic Zone.[Methods]An innovative methodology integrating grid discretization and distributed-parallel modeling techniques was employed.Combining dynamic modeling with 3D visualization,the approach introduced facies-controlled modeling into urban geological modeling practice to construct a high-fidelity 3D geological model.[Results]The model successfully achieves true 3D visualization of shallow subsurface strata(within 80 meters depth),clearly delineating the spatial distribution of geological units.By integrating multi-attribute models-encompassing lithology,geotechnical bearing capacity,and shear wave velocity-the model accurately characterizes the multi-dimensional features of the underground space.[Conclusions]The developed multi-attribute 3D geological model accurately represents the subsurface conditions.It effectively supports the assessment of urban underground space resources and site selection for major engineering projects,thereby establishing a precise data foundation and a robust basis for sustainable urban development.关键词
