Digital documentation of railway tunnel inspection in Austria

Civil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.
Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Rock Mass Anomaly Detection with a Variational Autoencoder in Tunnel Boring Machine Data

Civil Engineering Design, EarlyView.
Abstract This study presents an unsupervised machine learning approach to rock mass anomaly detection in tunnel boring machine operational data using a Variational Autoencoder combined with bidirectional Long Short‐Term Memory cells. The model was trained on TBM data from the Brenner Base Tunnel project, with minor faults and geotechnically relevant ...

In‐situ installation safety of post‐installed anchorages—Investigations on construction sites

Civil Engineering Design, EarlyView.
Abstract The sensitivity to reduced installation effort of post‐installed fastening systems is determined during the product qualification through robustness tests conducted under controlled laboratory conditions. Using the concept of required α‐factors, the installation safety factor γinst is determined and provided as an essential characteristic in ...

The Newly Discovered Pathway for Oxygen Evolution Reaction: In‐Situ/Operando Characterization Techniques for Catalyst Development

Carbon Energy, EarlyView.
This study introduces a newly discovered oxide path mechanism (OPM) for the oxygen evolution reaction (OER), emphasizing the role of in‐situ and operando characterization techniques in unraveling catalyst behavior under realistic conditions. The integration of advanced spectroscopic methods provides new mechanistic insights for the design of highly ...
