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 ... -
Behaviour of 60-year-old trial embankments on peat
Long, Michael; Paniagua Lopez, Ana Priscilla; Grimstad, Gustav; Sponås, Egil Berg Antoniazzi; Bjertness, Endre; Ritter, Stefan (Peer reviewed; Journal article, 2023) -

Building Deformation Caused by Tunneling: Centrifuge Modeling
Ritter, Stefan; Giardina, Giorgia; Franza, Andrea; DeJong, Matthew J. (Peer reviewed; Journal article, 2020)This paper investigates the deformation of buildings due to tunneling-induced soil displacements. Centrifuge model tests of three-dimensionally (3D) printed building models subject to a plane-strain tunnel excavation in ... -

Environmental impact assessments of geotechnical works
Størdal, Ingvild; Ritter, Stefan; Tann, Loretta von der (NGI-rapport;20200436-12-R, Research report, 2023-08-14)One of the major contributors to global carbon emissions is the construction sector. Using world environmental input-output tables from 2009, the total CO2-emissions from the global construction sector was calculated to ... -
First steps in the development of standardised processes for life cycle assessments of geotechnical works
Tann, Loretta von der; Størdal, Ingvild; Ritter, Stefan; Feizi, Siamak (Peer reviewed; Journal article, 2022) -

Physical modelling of pile drilling in sand
Lande, Einar John; Ritter, Stefan; Tyvold, Henning Fürst; Nordal, Steinar (Peer reviewed; Journal article, 2021)Drilling for foundation piles and tieback anchors through soils using a continuous casing to support the borehole is often referred to as "overburden drilling". Monitoring data from several case studies show that overburden ... -
