A Virtual Reality Monitoring System for Tunnel Boring Machines
Abstract: We present a VR system that allows to monitor tunnel constructions based on tunnel boring machines and segment linings. Today a variety of sensors and measurements are combined to control the process. This includes cutting disc forces, TBM navigation data, tunnel face images, deformations of the tunnel wall and more. This wealth of information is difficult to comprehend in its entirety by...

Deformation Monitoring of Tunnel Segments by 3D Laserscanning
Abstract: The contribution discusses the application of 3D laserscanning for the monitoring of tunnel segment deformation during TBM excavation. The measuring technology allows for scanning segmental linings directly from running TBMs with a high spatial and temporal resolution and accuracy. From static scans characteristic geometric parameters such as segment radius, orientation of segment axis, joint...

Drone Based Deformation Monitoring at the Tunnel Project Zentrum am Berg
Abstract: In the contribution a new drone based deformation monitoring system is presented that is currently developed by Geodata Group, 3GSM GmbH and Georesearch Forschungsgesellschaft mbH in the funded EUREKA research project Defdrone_3D and practically tested at the recently started Austrian tunnel project Zentrum am Berg (ZaB). The system is designed for monitoring the 3D displacements of structures...

New Developments for Roadheader Navigation
Abstract: The paper describes latest developments in the field of roadheader navigation and control. Next generation roadheaders incorporate high degrees of automation and allow remote data access if networked. To enable high-precision cutting and optimal roadheader use, the continuous measurement, processing and use of the absolute 3D tunnel position and orientation data of the machine and its cutting...

Using Cameras in TBM Cutterheads for Geological Documentation of the Tunnel Face
Abstract: The contribution presents a camera system for the geological documentation in mechanized tunneling that can be applied in TBM maintenance phases. The camera system is developed in the current R&D project TBMonitor and field-tested in a hard rock TBM drive of the Brenner Base Tunnel constructed by the ARGE Tulfes Pfons, a bidding consortium of Strabag AG and Salini Impregilo S.p.A. It provides...
