Framework-Attribute Coupled Modeling Technology Based on Geological Background:A Case Study of the Planning Area of Jinzhou City
摘要
Abstract
Three-dimensional geological models are indispensable visual data resources in the process of urban spatial development and utilization.Developing high-precision 3D geological models that integrate geological background conditions and spatial accuracy is a key breakthrough direction in the field of digital geology.This study took the planning area of Jinzhou City as an example and constructed a framework-attribute coupled modeling technology based on the modules of data organization,framework delineation,grid partitioning,and attribute assignment.Using borehole data,geological plan maps,and surface elevation as information sources for the model,the study employed a fault automatic splitting and aggregation algorithm to finely delineate fault plane morphology.Stratigraphic interfaces were generated based on the deformation field fracture restoration method to construct a geological interface framework model.Within the framework,the arrangement mode of grid nodes was selected according to the geological background of the strata to generate truncated rectangular grids,and attribute data was coarsened to the grid nodes where the sampling points were located.Variogram analysis was applied to analyze the distribution characteristics of existing attributes,and interpolation algorithms were matched to complete the attribute assignment of grid nodes within the model space.This technology integrates and improves the hierarchical relationships of multi-type geological information,achieving accurate reproduction of stratigraphic properties.The established model demonstrates significant accuracy in displaying the spatial intersection relationships of geological bodies and expressing geological background conditions.关键词
