糯扎渡水电站地下厂房开挖爆破振动测试

摘要

The analysis on blasting vibration test and its control in excavation of underground power-house of Nuozhadu hydropower station was carried out. By the full-scale blasting vibration test, the pa-rameter 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 develop-ment of an effective blasting method and suitable blasting parameters and provided reference for quality and schedule control.%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。
