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...

Development of Resource-efficient and Advanced underground technologies - DRAGON
Abstract: Goal of the DRAGON project is to achieve a higher grade of resource efficiency in tunneling and other underground construction processes by turning the excavation material into a valuable resource for other processes and sectors such as the cement, steel, ceramic or glass industries. The project sets out to solve this challenge by developing a prototype system for the automated online analysis,...

Disc Cutter Load Monitoring System - DCLM
Abstract: The DRAGON project (Development of Resource-efficient and Advanced Underground Technologies) is intended to improve resource efficiency in tunnelling processes by providing the excavated material as a raw material. The physical characterisation of excavated material can be detected by measuring the disc force. Entacher (2013) has shown that geological conditions in front of the cutterhead can...

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...

Research@ZaB as a Full-Scale Test Site for Geophysical Measurements
Abstract: Consecutive measurements play a key role in the successful construction of underground facilities. While surveying and deformation monitoring are considered as indispensable during tunnel excavation, the prediction of geological conditions ahead of the face and around the tunnel cross-section is a topic of ongoing research. Geophysical methods provide a useful tool to meet this challenge. Since...

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...
