A semi-automated and structured approach for creating a Geotechnical Synthesis Model

This article presents an innovative approach to structured information exchange in ground modeling, integrating geology, geotechnics, and hydrogeology. It proposes a data framework seamlessly merging the DAUB's modeling guidelines with the University of Innsbruck research. Addressing diverse data management challenges and ensuring interoperability, the workflow offers solutions for CAD- and interpolation-based modeling, enabling semi-automated generation of Geotechnical Synthesis Models with open file format export. Overcoming obstacles, the article introduces a uniform rasterization method, defining a tunnel-specific repository voxel (Tuxel). Results showcase a streamlined, semi-automated process using Autodesk Civil 3D® and Seequent Leapfrog Works®, enhancing data uniformity and enabling cross-project information exchange. This workflow provides practical solutions for collaborative ground modeling within BIM/TIM frameworks, fostering efficient and standardized data handling.
