This paper presents a regional 3D geological modeling method based on the stacking ensemble technique to overcome the challenges of sparse borehole data in large-scale linear underground projects. The proposed method transforms the 3D geological modeling problem into a stratigraphic property classification problem within a subsurface space grid cell framework. Borehole data is pre-pro... https://www.ealisboa.com/special-pick-CRB-Concept-Style-Spinning-Guides-Model-YG-best-find/
