摘要
从爆破地震具有的一般特点,探讨了不同爆破地震频率对反应谱的影响,当频率较高时其反应谱随周期的增长谱值下降快,但当爆破地震频率更低时,应对爆破地震作进一步频谱分析,如小波方法等,确保建筑物安全。
Through general features of blasting vibration, this text studys the impact analysis of frquency on blasting vibration response specturm. The conclusion is specturm value reduce quickly when frquency is very high, so the safety standard can meet the challenge, but when frquency is very low you need further study on specturm of blasting vibration such as walvet methodin order to protect the building safety.
