The traditional method of dynamic calculation of blasting vibration response of buildings has low accuracy. For this reason, a dynamic calculation method of building blasting vibration response based on differential equation is designed. The information contained in the original time domain is converted into the frequency domain by Fourier transform, and then the intensity index of blasting vibration wave is selected to analyze the main damage characteristics and sensitive damage parts of the building, evaluate the natural frequency of the building structure, and use differential equation to complete the calculation of blasting vibration response dynamics.The experimental results show that the calculation results of the above method are more accurate than that of the traditional method, which indicates that the method can meet the requirements of the dynamic calculation of the blasting vibration response of buildings.

传统的建筑物爆破振动响应动态计算方法精度较低。为此，设计了一种基于微分方程的建筑爆破振动响应动态计算方法。通过傅立叶变换将原始时域中包含的信息转换为频域，然后选择爆破振动波的强度指标来分析建筑物的主要损伤特征和敏感损伤部位，评估建筑物的固有频率实验结果表明，与传统方法相比，上述方法的计算结果更加准确。
