根据梯段爆破振动过程中物理量的复杂性,利用爆破振动相似律的基本原理建立了质点振动速度的相似准数方程,在选取指数回归形式的条件下得到了质点爆破振动速度回归经验公式,即萨道夫斯基修正公式。在溪洛渡水电站主厂房进行了现场爆破振动测试,分析了爆破振动速度衰减规律,回归结果较好的拟合了实测数据,利用工程实例验证了修正公式的合理性,为研究爆破振动速度衰减规律提供了一种新的选择。
According to the complexity of the physical quantities during the blasting vibration of the bench blasting section, the quasi-quasi-quasi-quasi-equation of the vibration velocity of the blasting point is established by using the basic principle of blasting vibration similarity law. The regression formula of the blasting vibration velocity is obtained under the condition of exponential regression, Sadovski correction formula. In the main workshop of Xiluodu hydropower station, the on-site blasting vibration test was conducted and the attenuation law of blasting vibration velocity was analyzed. The regression results fit well the measured data, and the engineering example was used to verify the rationality of the correction formula for the study of attenuation law of blasting vibration velocity A new choice.
