摘　　要：基于爆破地震效应的2个重要的因素:爆破地震本身的特性和爆破震动作用下建(构)筑物的结构响应特性,运用MATLAB小波分析工具箱的平台,利用现代的信号分析处理手段,从能量的角度出发,研究建(构)筑物在爆破震动作用下的能量响应,推导出响应速度的计算,探讨建立响应速度做为爆破震动安全评价指标。并结合工程实例说明了此方法比振速-频率相关的双因素安全判据更加有效。Based on the two important factors of blasting seismic effects ： the trait of blasting vibration itself and the structural response characteristics of construction （structure） of building under blasting vibration;using MATLAB wavelet analysis toolbox as platform, and making use of modern means of dealing with the signal analysis ; from the perspective of energy,studying the energy response of construction （structure） of building under blasting vibration, to deduce the calculation of the response rate, and try to use the response rate as the safety evaluation index about blasting vibration. Through working with engineering examples has proven that this method was more effective than the two-factor （velocity-frequency） security-related criteria.
