Stability assessment of rock slope at Hommelvik along E6
(Master thesis, 2022)Denne masteroppgaven omhandler den planlagte vegskjæringen ved Hommelvik som er en del av det pågående vegprosjektet E6 Ranheim – Værnes som er under bygging av Nye Veier. Den vil sannsynligvis bli rundt 450 m lang og ... -
Stability assessment of the asphalt concrete tunnel invert of Roskrepp hydropower project
(Master thesis, 2018)Rebuilding a hydropower plant into a pumped-storage plant in an underground tunnel, means that the water will rapidly change directions, instead of streaming evenly in one direction. This will cause extra water pressure ... -
Stability assessment of the Ryfylke subsea tunnel passing through weak rock mass
(Master thesis, 2022)Ved konstruksjon av bergrom er optimalisert bergsikring avgjørende for langtidsstabilitet og sikkerhet. Omfanget av bergsikring er hovedsakelig avhengig av bergmassekvalitet og sikringstradisjonene i det aktuelle området. ... -
Stability assessment of the underground powerhouse cavern for the Sach Khas hydroelectric project in Himachal, India
(Master thesis, 2016)Chenab basin in state of Himachal Pradesh has been opened for detailed study and development of hydropower projects. The government of Himachal Pradesh awarded development of the 260+7 MW Sach Khas project to L&T Himachal ... -
Stability Assessment of the Underground Powerhouse for the Tamakoshi V Hydroelectric Project
(Master thesis, 2022)Underground excavation presents several hazards and difficulties, especially when weak and schistose rock masses are involved. Excavated caverns in weak, deformable rock masses with thick rock cover are more prone to ... -
Stability assessment of underground parking cavern in Hammerfest
(Master thesis, 2014)This thesis addresses in detail the stability of the planned parking cavern in Hammerfest. It includes a review on recognized literature of support design for underground constructions, frost issues in tunnels, water inflow ... -
STABILITY ASSESSMMENT OF THE UNDERGROUND SETTLING BASIN CAVERNS OF SUPER MADI HYDROELECTRIC PROJECT,NEPAL
(Master thesis, 2012)Super Madi Hydrolectric Project (SMHEP) is located in Kaski District of Nepal. It is a run of river scheme with a installed capacity of 44 MW, net head of 295m and design discharge of 18 m^3⁄s.It has planned to build for ... -
Stability Challenges and Remedial Practices in Himalayan Hydropower Tunnels – A Review
(Journal article; Peer reviewed, 2024)The instability in tunnels is mainly affected by geological anomalies, rock mass quality, complex geological structures, active tectonics, and stress anisotropy. This review article presents challenges associated with ... -
Stability issues associated with the construction of underground caverns of Super Dordi Hydropower Project, Nepal
(Chapter, 2023)The rock mass is heterogeneous and makes underground space construction a challenge to engineers. The rock formation, mineralogical composition, degree of schistosity, and weathering, are the major factors that determine ... -
Stability of tunnels subject to plastic deformation – a contribution based on the cases from the Nepal Himalaya
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:305, Doctoral thesis, 2014)The purpose of excavating a tunnel is not fulfilled unless it is stable. One of the major causes of instability in tunnels is induced stresses around it. Tunnels excavated in weak and schistose rock mass below high overburden ... -
STABILTY ASSESSMENT OF HEADRACE TUNNEL SYSTEM FOR PUNATSANGCHHU II HYDROPOWER PROJECT, BHUTAN
(Master thesis, 2012)Bhutan is a small Buddhist country nested in the cradles of the eastern Himalayas. It has rugged mountainous terrains with altitudes ranging from 500 masl in its southern plains to 4500masl in the snowy capped mountains ... -
Stable and unstable capillary fingering in porous media with a gradient in grain size
(Peer reviewed; Journal article, 2022)Multiphase flows in complex porous networks occur in many natural processes and engineering applications. We present an analytical, experimental and numerical investigation of slow drainage in porous media that exhibit a ... -
State-of-the-art design guidelines in the use of unlined pressure tunnels / shafts for hydropower scheme
(Chapter, 2019)Technical soundness, cost effectiveness and long-term sustainability are the major issues that one should achieve while planning, designing, constructing and operating the hydropower schemes. With the changing world of ... -
Static and Dynamic Characterization of a Deep Overburden Shale
(Chapter, 2018)Since shales are the far most abundant overburden formation, understanding the geomechanical and rock physics behavior of shales is essential. We discuss a particular deep overburden shale in light of a thorough static and ... -
Static and dynamic stability analyses of the 800m high Åknes rock slope, western Norway
