Cyclic fatigue in unlined hydro tunnels caused by pressure transients
Neupane, Bibek; Panthi, Krishna Kanta; Vereide, Kaspar (Peer reviewed; Journal article, 2021)Regulated hydropower is currently the most capable load balancing technology for the future renewable energy system which will be characterized by a large share of unregulated energy from solar and wind power. Increased ... -
Hydraulic Transient Impact on Surrounding Rock Mass of Unlined Pressure Tunnels
Ghimire, Sanyam; Panthi, Krishna Kanta; Vereide, Kaspar Vatland (Peer reviewed; Journal article, 2023)The frequent pressure pulsations due to hydraulic transients in hydropower plants induce cyclic loading on the rock mass that may contribute to increased instances of block falls and increased risk of tunnel collapse over ... -
Instrumentation and pore pressure monitoring technique for unlined tunnels of Norwegian hydropower projects – a case study
Neupane, Bibek; Panthi, Krishna Kanta; Vereide, Kaspar (Chapter, 2019)The power market in Norway was deregulated in 1991 and have caused power plants to operate with more frequently varying loads within short time periods. Such operation causes significant pressure fluctuations and unsteady ... -
Operation of Norwegian Hydropower Plants and Its Effect on Block Fall Events in Unlined Pressure Tunnels and Shafts
Neupane, Bibek; Vereide, Kaspar; Panthi, Krishna Kanta (Peer reviewed; Journal article, 2021)The main objective of this study is to investigate the effect of hydropower plant operation on the long-term stability of unlined pressure tunnels of hydropower plants in Norway. The authors analyzed the past production ...
