中文摘要：

爆破地震效应研究的中心话题就是如何对爆破地震的危害作出准确而又科学的评价。结合建筑物能量破坏机理,考虑爆破地震能量分布及建筑物动力响应特性,构造了基于＂等效峰值能量＂（EPE）的爆破地震安全评价方法。在相关研究的基础上,提出了EPE的爆破地震安全评价指标,并研究了EPE及等效速度的计算过程,探讨了不同爆源形式下的EPE简化计算方法,认为采用以等效速度表示的EPE指标来衡量爆破地震的危害程度是可行的,它较振速-频率相关的安全判据更能全面反映爆破地震危害的本质,并且具有很强的可操作性。

英文摘要：

The most important issue for the researches on blast-induced seismic effects is to assess the damage induced by blasting vibration accurately and reasonably.Combining the energy damage mechanism and considering the distribution of blast-induced seismic energy and dynamic response characteristics of structures,a method for safety assessment on blasting vibration is proposed based on the equivalent peak energy（EPE）.On the basis of relevant research results,the criterion based on EPE is put forward,and its computational procedure and equivalent velocity are studied.Furthermore,the simplified method of EPE for seismic induced by different types of blasting resources is studied.The research suggests that it is feasible for the equivalent velocity of EPE to evaluate the damage induced by blasting vibration.The criterion based on EPE reflects the essence of blasting vibration damage more comprehensively than the safety criterion considering the effect of frequency.And it can be realized easily.
