Strindheimtunnelen - Stabilitetsanalyse og vurderinger av påhugget ved dagsone vest
Gylland, Asgeir Samstad (Master thesis, 2012)Som del av nye E6 fra Trondheim til Stjørdal skal det bygges en ny tunnel fra Nyhavna til Strindheim. Strindheimtunnelen vil ved ferdigstillelse i 2014 bestå av to parallelle løp med tverrsnitt T9,5 og lengde 2,5 km. Ved ... -
Studie av forinjeksjon i Strindheimtunnelen
Isachsen, Guro (Master thesis, 2015)Vann i bergmassen er en stadig utfordring ved underjordsdrift. I tillegg til at vanninntrengning under driving reduserer inndriften og arbeidsmiljøet på stuff, kan lekkasjene også medføre senkning av grunnvannstanden rundt ... -
STUDY ON MATERIAL PROPERTIES AND TESTING OF VARIOUS ROCK TYPES, DEVELOPMENT OF INVESTIGATION PROCEDURE AND TEST METHODOLOGY FOR FUTURE PROJECTS
Selen, Lena (Master thesis, 2017)This master thesis aims to provide insight and qualitative information about swelling mechanisms in volcanic rocks, in particular the swelling of rocks related to hydropower water tunnels. Additionally, traditional laboratory ... -
Study on the development of pumped storage hydropower project at Snåsa
Dahle, Torstein Jørgensen (Master thesis, 2014)An increasing power demand and a transition towards more renewable energy sources have led to an increasing development of wind farms. Wind farms produce unregulated power which may not be available when it is needed. ... -
Study on the long-term stability issues of the headrace tunnel of Ulset Hydropower Project
Døvle, Linn (Master thesis, 2019)Den norske vannkraftindutrien er et resultat av over hundre år med erfaring fra utvikling av design og bygging av vannkraftprosjekter. Erfaringene har resultert i en norsk spesialitet, ufôrete trykktunneler og -sjakter. ... -
Study on the swelling potential of some selected rocks
Skippervik, Catrine Pettersen; Panthi, Krishna Kanta; Dahl, Filip Erik Bo (Chapter, 2014)For clay minerals the swelling mechanisms and factors influencing on the swelling potential is widely explained and confirmed through comprehensive research. When it comes to intact rocks there are questions regarding both ... -
Study on the Swelling Potential of some Selected Rocks
Pettersen Skippervik, Catrine (Master thesis, 2014)Weaknesses zones consisting of sheared and fractured rock mass have a swelling potential in the presence of clays rich in montmorillonite. When it comes to intact rocks there are questions regarding both the swelling ... -
Suspended Sediment Source and Transport Mechanisms in a Himalayan River
Ghimire, Sanyam; Singh, Umesh; Panthi, Krishna Kanta; Bhattarai, Pawan Kumar (Journal article; Peer reviewed, 2024)The process of estimating sediment load has been a daunting issue in hydraulics and the water resource field. Several methods exist for predicting the sediment load in a catchment or river, but the majority of these methods ... -
Sustainable Flexibility Metrics : Measuring economic flexibility relative to environmental and structural sustainability
Mathisen, Siri Gulaker; Bjørnås, Kristine Lund; Panthi, Krishna Kanta; Aronsen, Tonje; Majaneva, Markus; Tselika, Kyriaki (Hydrocen rapport;, Research report, 2023) -
Swelling pressures of some rocks using different test procedures
Selen, Lena; Panthi, Krishna Kanta; Vergara, Maximilliano R. (Chapter, 2018)There are no clearly defined rules for the investigation procedures of swelling rocks. Difficulties are generally met for characterization and testing of swelling rocks and for prediction of the response to tunnel excavation. ... -
The use of Self Supporting Capacity of Rock Mass for Sustainable Hydropower: An Analysis of the Middle Marsyangdi Headrace Tunnel, Nepal
Panthi, Krishna Kanta; Shrestha, Kiran Kumar (Journal article; Peer reviewed, 2010)The history of hydropower development in the Himalaya indicates that many tunnels have suffered from cost overruns and delays. These issues are directly dependent on the quality of rock mass and the permanent rock support ... -
Topographic Effect in the Selection of Unlined Pressure Tunnels / Shafts - A Review of a case from Nepal Himalaya
Basnet, Chhatra Bahadur; Panthi, Krishna Kanta (Chapter, 2017)The design principle behind unlined pressure tunnels/shafts is that the minimum principle stress should be higher than the hydrostatic head acting on the periphery of tunnel/shaft. So, reliable estimation of in-situ stresses ... -
TUNNELING ASPECTS OF THE WATERWAY SYSTEM AND STABILITY ASSESSMENT OF THE POWERHOUSE CAVERN FOR THE MINAS-SAN FRANCISCO HPP
Encalada, Jhonny (Master thesis, 2018)The future trend of energy supplies is gradually moving from fossil fuels to renewable and sustainable energy sources. In this context, hydropower is one of the best options to supply the base load and meet the energy ... -
Tunnelling challenges in Nepal
Panthi, Krishna Kanta (Chapter, 2004)Nepal is a landlocked mountainous country with a population of approximately 23 millions. Being steep in topography and having many rivers originating from the glaciers of the Himalaya, Nepal has been gifted in the field ... -
Turnkey Contract - A Management Challenge under Himalayan Geological Condition
Panthi, Krishna Kanta (Journal article; Peer reviewed, 2016)Himalayan geology poses special attention and tunnelling challenges, which are associated to the engineering geological conditions in the rock mass. Completing tunnelling project within scheduled contractual time is an ... -
Uncertainty Analysis for Assessing Leakage Through Water Tunnels: A Case from Nepal Himalaya
Panthi, Krishna Kanta; Nilsen, Bjørn (Journal article; Peer reviewed, 2010)Water leakage problems in unlined or shotcrete lined water tunnels are not new issues. In many occasions severe water leakage problems have been faced that not only have reduced the stability of the rock mass, but also ... -
Uncertainty analysis for assessing rock mass quality and water inflow in hard rock subsea tunnels
Panthi, Krishna Kanta (Chapter, 2009)In many occasions considerable discrepancies have been found between predicted and actual rock mass conditions, resulting significant cost and time overrun. Finding innovative solutions for quantifying geological uncertainties ... -
Uncertainty analysis of tunnel squeezing for two tunnel cases from Nepal Himalaya
Panthi, Krishna Kanta; Nilsen, Bjørn (Journal article; Peer reviewed, 2007)Weak rocks such as shale, slate, phyllite and schist, and the rock mass of weakness/fault zones are incapable of sustaining high tangential stress. Severe tunnel squeezing is therefore common in the tectonically active ... -
