A Displacement-Based Theory for Predicting the Support Force on the Shield Tunneling Surface in Sandy Soil Layers

Advances in Civil Engineering, 2021
Due to the poor stability of the loose sandy soil layer, if the support force is not properly controlled during the construction process of the shield tunnel using the earth pressure balance method, it is easy to cause the ground to collapse or uplift ...

The Domus Nozze D'Argento in Pompeii: Structural Diagnosis Using Geophysical Methods

Archaeological Prospection, EarlyView.
ABSTRACT Monitoring of ancient buildings is an issue of great interest in view of a proper restoration. This paper describes the noninvasive monitoring of the Domus Nozze D'Argento in Pompeii. The Roman house, as occurred for many other buildings in Pompei, was buried in the ash from the 79 ad eruption of Mount Vesuvius.

SARchaeological Prospection: Synthetic Aperture Radar for the Reconstruction and Mapping of Temperate Floodplain Environments

Archaeological Prospection, EarlyView.
ABSTRACT Temperate river floodplains present a significant challenge for archaeologists, as cultural and palaeoenvironmental remains are often difficult to locate but can be exceptionally well preserved, especially where groundwater levels are high. In these alluvial environments, the deposition of thick, fine‐grained sediments has potential to deeply ...

Ensemble‐based soil liquefaction assessment: Leveraging CPT data for enhanced predictions

Civil Engineering Design, Volume 7, Issue 1, Page 23-35, March 2025.
Abstract This study focuses on predicting soil liquefaction, a critical phenomenon that can significantly impact the stability and safety of structures during seismic events. Accurate liquefaction assessment is vital for geotechnical engineering, as it informs the design and mitigation strategies needed to safeguard infrastructure and reduce the risk ...

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 ...
