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.
