Due to the severe squeezing and deformation, the tunnel cross section has narrowed considerably ... -
Analysis of the Deformation Behavior at the Underground Caverns of Neelum Jhelum HPP, Pakistan
Vestad, Magni Larsen (Master thesis, 2014)Many risks and challenges are associated with large scale underground projects. Stability issues are typically related to high stresses around the opening. Excavations will change the existent stress regime in the ground, ... -
Analysis of the measured pore pressure and hydraulic data from Roskrepp hydropower plant
Ghimire, Sanyam (Master thesis, 2023)There is change in operational regime of hydropower power plants in Norway after deregulation of energy markets and recent integration of renewable and unregulated energy sources such as wind and solar in an energy mix. ... -
Analysis of the plastic deformation behavior of schist and schistose mica gneiss at Khimti headrace tunnel, Nepal
Shrestha, Pawan Kumar; Panthi, Krishna Kanta (Journal article; Peer reviewed, 2014)The Khimti headrace tunnel experienced instability related to tunnel deformations in several tunnel stretches through mica schist and schistose mica gneiss rock mass. The monitored convergence pattern indicated that the ... -
Analysis of unlined pressure shafts and tunnels of selected Norwegian hydropower projects
Basnet, Chhatra Bahadur; Panthi, Krishna Kanta (Journal article; Peer reviewed, 2018)Norwegian hydropower industry has more than 100 years of experiences in constructing more than 4000 km-long unlined pressure shafts and tunnels with maximum static head of 1047 m (equivalent to almost 10.5 MPa) reached at ... -
Analysis on the Dynamics of Burst Debris Flood at the Inclined Pressure-Shaft of Svandalsflona Hydropower Project, Norway
Panthi, Krishna Kanta (Journal article; Peer reviewed, 2014)Longterm stability of the waterway system of the hydropower plants is crucial and should not be underestimated. The compromise may result in severe economic consequences related to revenue loss caused by the plant closedown ... -
