摘　　要：对糯扎渡水电站地下厂房开挖爆破振动测试与控制进行研究,通过现场施工开展有针对性的生产性爆破振动试验,了解装药参数与爆破振动速度衰减的规律,掌握开挖爆破对围岩及其他部位的动力损伤特性,寻求一套科学有效的爆破方法和爆破参数,为保证施工质量及加快施工进度提供科学依据。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.
