THE RELATIONSHIP BETWEEN GROUND VIBRATION, PARTICLE SIZE AND SEISMIC ENERGY CAUSED BY BLASTING

Abstract

In this study, the relationship between ground vibration, particle size distribution and energy distribution caused by blasting were investigated. For this purpose, ground vibrations were measured by using ground vibration monitors, Seismic Energies were calculated according to ground vibrations and particle size distribution were analyzed by using Split Desktop software. After these measurements and simulation, The relationship between PPV and SD which is the most widely used relationship in literature to predict the peak particle velocities were established with strong correlation coefficient (r = 0.89) by log-linear regression analysis. In order to improve this prediction equation, another relationship which takes d50 and Seismic Energies into account in addition to SD and PPV were tried to be established. This new relationship were obtained with a strong reasonable correlation coefficient (r = 0.98) by applying multiple regression analysis with SPSS. It can be seen that the correlation coefficient of the latter relationship is rather stronger than the correlation coefficient of former relationship. Therefore, the more accurately predictability of PPV was asserted with this relationship.
