Renkun Wang

Engineering 2016, Volume 2, Issue 3, Pages 350-359 doi: 10.1016/J.ENG.2016.03.012

Abstract:

Starting with the Ertan arch dam (240 m high, 3300 MW) in 2000, China successfully built a total ofseven ultra-high arch dams over 200 m tall by the end of 2014.The design and construction of these 300 m ultra-high arch dams posed significant challenges, due tohigh water pressures, high seismic design criteria, and complex geological conditions.m ultra-high arch dams, including the strength and stability of foundation rock, excavation of the dam
