Research on Blasting Vibration Safety Assessment Parameters

Abstract:

Based on the fluctuation or vibration failure mechanism of structures under blast vibration, the relationship between the amplitude, frequency of blasting vibration and the stress, strain (deformation) of structures is studied. The assessment method of blasting vibration effects is determined. The results indicate that under the fluctuation failure mechanism, the peak stress and strain of structures are proportional to the peak particle vibration velocity. The peak particle velocity (PPV) can be used to evaluate blasting vibration effects, while under vibration failure mechanisms, PPV, the main frequency and the natural frequency of structures must be considered for blasting vibraton effect safety assessment. The peak particle vibration acceleration should not be a separate evaluation parameter for blasting vibraton effects.
