Abstract: Abstract:The general situation of the underground powerhouse project of Elephant Trunk Hill Hydropower Station and the geologic features were introduced. The quality control measures of the rockanchored beam excavation of the underground powerhouse were expounded. The construction scheme of the rockanchored beam excavation was put forward. According to the bursting test result, the rational parameters were determined. The remained halfhole rate, the flatness and the bodily form of the excavation surface meet the specification and design requirement. The conclusion of the united acceptance inspection is“excellent”.
