Before design and construction, particularly underground, it is essential to know the geological conditions well. Nowadays as in many other fields 3D modelling is a very powerful and helpful tool in geology and geotechnics. The advantages of 3D modelling in geology are convincing: In the past, 2D geological maps and sections were of common use and it could sometimes be difficult to conceive a 3D picture of the underground conditions from the 2D images. With modern software, geological 3D models can be generated easily. Once a 3D model is established, the underground situation is more comprehensible and inconsistencies in geological interpretation are immediately apparent. 2D sections can also be produced with little effort at any position. The model can also be used as a geological database for the project. All available geological and geotechnical information like maps, sections, borehole data and lab test results can be attached to the model. The generation of a geological 3D model will be explained through the example of the Karawanken Tunnel, northern section.
