摘要
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。
Considering the complexity of physical quantities during the process of blasting vibration,the similarity criterion equation was built based on the basic principle of similarity law of blasting vibration.Blasting vibration velocity regression equation can be obtained using the exponential regression form,which is Sadaovsk modifier formula.The blasting vibration test was done in the main power house of Xiluodu hydrostation,and the analysis of the blasting attenuation characteristics shows that the regression results can appropriate reflect the measured data.The engineering example validates the rationality of the modified equation.This paper provides a new formula for the study of blasting vibration velocity attenuation.
