A Supernal Security Regression Method of Blast Vibration

摘要：

　　Least squares fitting is usually adopted in regression of blast vibration.On the basis of Sadovs formula,which is invented by a former Soviet Union scholar named Steve Sadove,the regression elements are ln(v) and ln(3√Q/R) and they linearly increase each other.Actually,if ln(v) and ln(3√Q/R) are analyzed directly,there are 50% data points over the regression line and 50% data points below.So 50% actual measured data of blast vibration velocity are unsafe for the regression equation.So we introduce regression safety coefficient f(0<f<l) in the regression analysis in this paper and find a new regression method which is safer.The f is different in different projects,such as f=0.9 means 90% measured sample points is below the regression line and 10% is up.So the veracity of blasting safety is improved.We can see,the new regression method contract with common method,the topography and geological conditions coefficient K from blasting points to fixed point is increase by f,and the damping coefficient α is all the same.That means slope of regression line is invariant while intercept increase along with f.
