The first presentation of the VR application Geotunnel at this year’s Geomechanics Colloquium in Salzburg was of great interest. The application enables a virtual tour in a tunnel excavation by means of a VR headset (HTCvive). For example, geotechnical measurement data and their temporal development (3D displacement measurements, extensometers, etc.) can be analyzed together with excavation data (e.g. face images).
