| Abstract:Reinforced support was made for the side wall, altered rock and large fault of the main engine compartment, main transformer room and bus cavern in underground powerhouse of Jinping 1 hydropower station by the horizontal pre-stressed anchor. In the construction process of pre-stressed horizontal anchor, according to the different geological formations, hole deviation was basically solved by strict control methods with continuous improvement. |
