Abstract
Scaled distance equations used for estimating peak particle velocity have been developed by some researchers. The most widely used equation among these is the equation developed by Duvall and Fogelson. However, the equation has not exactly estimated the peak particle velocity correctly. In this study, peak particle velocity values were measured by a number of blast tests that were conducted in four different sites by using a vibration meter. Scaled distance values for each blast test were calculated according to the equation proposed by Duvall and Fogelson. Subsequently, a new equation that calculates the scaled distance was proposed. The proposed equation gave more realistic values than the equation proposed by Duvall and Fogelson.
