Abstract
Three-dimensional visual modeling of surface-stratum-structure is an inevitable requirement for intelligent geotechnical engineering. However, the heterogeneity of surface, stratigraphic and structural data sources and modeling methods leads to incompatibility of model attributes. Only a few studies have directly realized the three-dimensional (3D) modeling of surface-strata-structure. In order to solve this problem, this study uses the Kriging interpolation method based on relative elevation to realize the fusion of borehole data and surface data, and establishes a 3D surface-strata model. The Boolean difference set operation based on the bounding box method is used to propose a geometric fusion method for the 3D surface-strata-underground structure model. In addition, an attribute fusion method of 3D surface-stratum-underground structure model is introduced by using variable storage…
