3D Numerical Modeling of Rock Mass Failure in an Uplift Test of a Rock Anchor with Focus on the Role of Rock Joints
Manquehual Mery, Cristobal Javier; Li, Charlie Chunlin; Shabanimashcool, Mahdi; Grindheim, Bjarte; Lia, Leif (Journal article; Peer reviewed, 2025)This paper aims to numerically study the failure mechanisms of the rock mass during the uplift test of a rock anchor installed in limestone. The rock anchor consisted of a smooth tendon, with short threaded sections at ... -
Full-scale pullout tests of rock anchors in a limestone quarry focusing on bond failure at the anchor-grout and grout-rock interfaces
Grindheim, Bjarte; Li, Charlie Chunlin; Høien, Are Håvard (Peer reviewed; Journal article, 2023)Rock anchors are a common safety measure for stabilising large-scale infrastructure, such as bridge towers, retaining walls, rock slopes and windmills. There are four principal failure modes for rock anchors: (a) tensile ... -
Investigating Load Arches and the Uplift Capacity of Rock Anchors: A Numerical Approach
Grindheim, Bjarte; Trinh, Nghia Quoc; Li, Charlie Chunlin; Høien, Are Håvard (Journal article; Peer reviewed, 2024)Rock anchors, which can withstand substantial forces and are essential for securing the foundations of the built environment, can fail due to steel tensile failure, bond detachment, or rock mass fracturing through uplift. ... -
Laboratorietester av blokkmodeller og opptrekkstester i felt for å undersøke bergmassens atferd når den utsettes for belastning fra forankringer
Angell, Brage (Master thesis, 2023)Fjellankere, også kalt strekkforankringer eller bare forankringer, består av lastbærende komponenter stag eller kabler som brukes til å stabilisere storskala infrastrukturer i bergmasser og til å forsterke undergrunnen, ... -
Load Arching and Uplift Failure around Rock Anchors: Experimental investigation on rock anchor failure modes, load transfer mechanisms and load capacity
Grindheim, Bjarte (Doctoral theses at NTNU;2024:402, Doctoral thesis, 2024)Rock anchors play an important role in geotechnical engineering, providing stability and reinforcement to large-scale infrastructures. A comprehensive literature review revealed that the knowledge and design practices of ... -
Mapping of Shrinkage Cracks with Dye Penetrant on Sprayed Concrete Cores
Grindheim, Bjarte (Master thesis, 2020)Ein ny metode for kartlegging av svinnriss på sprøytebetongkjernar blei testa i denne masteroppgåva. Dette vart gjort med penetrantvæske med fargemiddel. Metoden er ein ikkje-destruktiv test metode på sprøytebetongkjernar. ... -
Small Block Model Tests for the Behaviour of a Blocky Rock Mass Under a Concentrated Rock Anchor Load
Grindheim, Bjarte; Aasbø, Karsten Sannes; Høien, Are Håvard; Li, Charlie Chunlin (Peer reviewed; Journal article, 2022)Rock anchors are used to stabilise large-scale infrastructure such as the foundations of high buildings or road cuts, and their failure could lead to severe economic and social consequences. A rock anchor can fail in one ...
