| Abstract: | Based on multivariate linear regression analysis, attenuation equations were established for blast-induced vibration of residential house influenced by velocity and frequency, and a method was proposed for testing regression effect. The results analysis showed that the accuracy of prediction with velocity-frequency regression equations is 4% higher than that with single-velocity regression equation. It is further verified that frequency is very important in the analysis of building response to blast-induced vibration. This conclusion will be significant in guiding safety production in open-pit mine. |
