An ArcGIS toolbox for the probabilistic performance-based assessment of surface building damage in large-scale urban excavations
Zhao, J.; Lysdahl, Asgeir Olaf Kydland; Ånes, Eivind Wiik; Piciullo, Luca; Ritter, Stefan; DeJong, M.J. (Chapter, 2024) -
Assessing potential building damage caused by leakage to urban tunnels
Langford, Jenny; Ritter, Stefan; Lysdahl, Asgeir Olaf Kydland; Ånes, Eivind Wiik; Piciullo, Luca (Peer reviewed; Journal article, 2023)Building damage is a major risk for urban tunnelling. In areas with soft soil conditions, water ingress to bedrock tunnels can cause significant pore pressure reduction, consolidation settle-ments and damage to nearby ... -
Assessment of building damage due to excavation-induced displacements: The GIBV method
Piciullo, Luca; Ritter, Stefan; Lysdahl, Asgeir Olaf Kydland; Langford, Jenny; Nadim, Farrokh (Peer reviewed; Journal article, 2020)This paper presents an original methodology for the rapid assessment of “potential” building damage caused by an excavation. The combination of the Ground-work Impact (GI), in terms of induced greenfield displacements, and ... -
Forensic investigation of quick clay landslide released by construction work at Asak, Norway
Heyerdahl, Håkon; Amdal, Åse Marit Wist; Frauenfelder, Regula; Sverdrup-Thygeson, Kjetil; Lysdahl, Asgeir Olaf Kydland (Chapter, 2024) -
Geoelectrical properties of saline permafrost soil in the Adventdalen valley of Svalbard (Norway), constrained with in-situ well data
Tavakoli, Saman; Gilbert, Graham Lewis; Lysdahl, Asgeir Olaf Kydland; Frauenfelder, Regula; Forsberg, Cathinka Schaanning (Peer reviewed; Journal article, 2021) -
Integrated bedrock model combining airborne geophysics and sparse drillings based on an artificial neural network
Lysdahl, Asgeir Olaf Kydland; Christensen, Craig; Pfaffhuber, Andreas Aspmo; Vöge, Malte; Andresen, Lars; Skudal, Guro H.; Panzner, Martin (Peer reviewed; Journal article, 2021)Cost overruns caused by unforeseen geological challenges are commonplace for large infrastructure projects. Thorough ground investigations can reduce this risk, but geotechnical drillings and laboratory test are expensive ... -
Modelling of shallow landslides with Machine Learning algorithms
Liu, Zhongqiang; Gilbert, Graham Lewis; Cepeda, Rivera Jose Mauricio; Lysdahl, Asgeir Olaf Kydland; Piciullo, Luca; Haugland, Heidi Hefre; Lacasse, Suzanne (Peer reviewed; Journal article, 2020)This paper introduces three machine learning (ML) algorithms, the 'ensemble' Random Forest (RF), the 'ensemble' Gradient Boosted Regression Tree (GBRT) and the MultiLayer Perceptron neural network (MLP) and applies them ... -
Peatland Volume Mapping over Resistive Substrates with Airborne Electromagnetic Technology
Silvestri, Sonia; Christensen, Craig; Lysdahl, Asgeir Olaf Kydland; Anschütz, Helgard; Pfaffhuber, Andreas Aspmo; Viezzoli, Andrea (Peer reviewed; Journal article, 2019)Despite the importance of peatlands as carbon reservoirs, a reliable methodology for the detection of peat volumes at regional scale is still missing. In this study we explore for the first time the use of Airborne ... -
Resistivity and chargeability survey for tunnel investigation: a case study on toxic black shale in Norway
Bazin, Sara; Lysdahl, Asgeir Olaf Kydland; Viezzoli, Andrea; Gunther, T; Anschütz, Helgard; Scheibz, Jürgen; Pfaffhuber, Andreas Aspmo; Radic, T; Fjermestad, Halldis (Journal article; Peer reviewed, 2017)In the past few years, the focus on Alum shale hazards and the need for efficient mapping tools have increased in Norway. Alum shale is highly toxic and poses a substantial obstacle to infrastructure development such as ... -
The use of the GIBV method for monitoring the effects of urban excavations on built heritage
Piciullo, Luca; Ritter, Stefan; Lysdahl, Asgeir Olaf Kydland; Tann, Loretta von der; Langford, Jenny; Nadim, Farrokh (Chapter, 2022)
