Abstract: The analysis on blasting vibration test and its control in excavation of underground powerhouse of Nuozhadu hydropower station was carried out. By the full-scale blasting vibration test, the parameter for explosive charge and vibration attenuation laws were obtained and the dynamic damage caused by excavation blasting on surrounding rock was observed. As well, this paved a way for development of an effective blasting method and suitable blasting parameters and provided reference for quality and schedule control.
Key words: Nuozhadu hydropower station, underground powerhouse, blasting vibration test
