Evaluation of in-situ stress state along the shotcrete lined high-pressure headrace tunnel at a complex Himalayan geological condition
Basnet, Chhatra Bahadur; Panthi, Krishna Kanta (Peer reviewed; Journal article, 2021)The Himalayan region is renowned with its complex topography and active tectonic movement, which causes accumulation and sudden release of strain energy instigating changes in the in-situ stress state. This paper evaluates ... -
Evaluation of Powerhouse Cavern for the SachKhas Hydroelectric Project in Himachal, India
Rathore, Ajender; Panthi, Krishna Kanta (Journal article; Peer reviewed, 2017)Evaluation of an underground powerhouse cavern’s stability is a challenging task and needs to be carried out carefully by taking care of its location, orientation and dimensioning. This article deals with the stability ... -
Evaluation of rock bursting phenomena in a tunnel in the Himalaya
Panthi, Krishna Kanta (Journal article; Peer reviewed, 2012)Tunnels passing beneath deep rock cover(overburden) are subject to instabilities caused by induced rock stresses. In a relatively unjointed massive rock mass the instability is associated with rock spalling/rock bursting, ... -
Evaluation of Seismic Events Occurred after Filling and Drawdown of the Reservoir at Song Tranh 2 HPP in Vietnam
Trinh, Quoc Nghia; Panthi, Krishna Kanta (Journal article; Peer reviewed, 2014)Reservoir-induced earthquakes are a challenging issue for hydropower, and have occurred at many sites around the world. However, each event is unique in itself and depends on the geo-tectonics and geo-hydrology of the area ... -
Evaluation on stability condition along the headrace tunnel of Kulekhani-III Hydroelectric Project
Shrestha, Nitesh (Master thesis, 2020)With over 90% of the country’s total electricity generation capacity generated by hydropower plants, Nepal is heavily dependent on hydro resources to meet its energy demands. Best use of water using the shortest and the ... -
Evaluation on the Efect of Pressure Transients on Rock Joints in Unlined Hydropower Tunnels Using Numerical Simulation
Neupane, Bibek; Panthi, Krishna Kanta (Peer reviewed; Journal article, 2021)Frequent pressure transients are identified as the cause of block failures in many unlined hydropower tunnels.
