| Abstract: | Blocking water loss in large- discharge and high flow-rate karst caves is a difficult problem involved in all projects in karst terrains. This paper describes the most precise CT acquisition technique among drilling and grouting techniques using models and bags that have been sucessfully applied in the project dealing with the leakage of the fourth narrow alley hydroelectric installation over the Maotiao River and the project controlling water burst in the workshop foundation ditch of the Yinzidu hydroelectric installation over the Sancha River in Guizhou Province. |
