Safety Assessment Method Based on Response Spectrum Analysis of Building Structures to Blasting Vibration
It is Founded that SR can comprehensively reflect the general effect of the blasting vibration and the Influences of Structural damage of vibration by structure dynamic characteristics. The computation and the analysis of 132 groups blasting vibration data indicates that probability of destroying of general houses by blasting vibration increases Significantly when SR2≤5,5.and then the SR2≤5,5 is used as a supplementary of the type II construction. On this basis, the unified sccurity criterion of blasting vibration safety is initially founded through introducing the concept of Pis of structures blasting vibration speetrum safety factor.
