建筑物对爆破振动中不同频率能量成分的响应特征
Response characteristics of structures to the different energy components of blasting vibration
The effect of blast-induced seismic on structures can be considered as a transferred and transformed process of the energy, which relates to the dynamic response of structures. Based on structure dynamic theory, the response characteristics of structures to the different energy components of blasting vibration are studied with a typical example project. The result shows that the amplification effect of the structures to energy content with different frequency is obviously selective. Further discussion about the safety criterion considering the effect of frequency shows that when the safety criterion for blasting vibration is proposed, it is necessary to give consideration to both characteristics of blast-induced seismic and dynamic response characteristics of structures, and the energy component of blasting vibration which has the same frequency as the structure must be paid more attention to.
