摘要
根据国家爆破安全规程及国内外研究成果,通过对硗碛水电站地下厂房母线洞爆破进行振动测试,采用萨道夫斯基公式回归出该地形地质条件下的爆破衰减规律,并结合该水电站地下厂房开挖的特点,提出了爆破振动破坏标准,得出了岩锚梁新浇混凝土区爆破安全振动控制参量,并提出了相应的爆破降振措施,将该措施和控制参量应用到后期的爆破开挖中,从后期的监测数据和工程实践来看,研究成果得到了很好的应用,保证了工程爆破的安全顺利施工。
On the basis of blasting safe rides and research achievements, the attenuation formula of blasting vibration wave is obtained according to testing in the site. According to features of underground chamber of Qiaoqi hydropower station, damage standards of blasting vibration based on the blasting safety control and parameters of new cast-in-situ concrete of the underground chamber are gained. In the light of construction characteristics of the underground chamber, the control measures of the blasting are proposed. The construction effects of the project indicates that research achievements of this paper are effectively applied in the project, and the blasting of the project is smoothly implemented.
