李家峡导流隧洞快速掘进施工中的新技术
New Technology in Construction of Lijiaxia DiversionTu mna with High- Speed Drivage
摘要
Abstract
The geological condition of the diversion tunnelof Lijiaxia Hydropower Station is very complicated.During construction, the suspended crown concrete liningtechnique of the “New Austrian Tunneling Method” wassuccessfully used for the first time in China. Theconstruction technologies such as overlapping excavation,overlapping placement and so on have been developed andapplied with a good result. The collapses in the diversion tunnel under weak geological conditions have been controlled to a maximum, and the advance speed of largesection diversion tunnel has been raised to a high level in China.
