| 摘 要： | 为了分析影响爆破振动频率的各个因素，为结构物爆破振动安全评价提供可推依据。通过现场爆破振动测试，结合实际分析了频率在爆破振动中的作用，并分析了结构物爆破振动响应的频谱特性，发现爆炸能量、起爆段数、距离以及传播介质对爆破振动频率都有不同程度的影响。通过对爆破振动频率影响因素的分析，指出在爆破振动的测试分析中应充分注意到爆破条件和测试条件的变化。

| Abstract: | In order to analyze each element affecting blasting vibration frequency and provide reliable basis for the evaluation of structures blasting vibration safety,through blasting vibration testing on the spot,the thesis has studied the function of frequency in the blasting vibration in practice,and studied the frequency chart characteristic of the response of structure under blasting vibration.It has discovered the influence of blasting capacity,blasting delay interval,distance and spread substance on blasting vibration frequency.Through the analysis of the affecting factors of blasting vibration frequency,the paper points out that the transformation of blasting condition and test condition should be paid full attention to in the measurement analyses of explosion vibration. |
