汶川大地震远区实测振动速度波形分析
|
摘要
汶川大地震发生时,在向家坝水电站工地监测到了由地震产生的振动速度,通过对大地震产生的振动速度实测波形的分析,得到了振动速度频率、振动峰值、振动加速度、位移等的变化情况,这对工程爆破振动控制标准的研究具有一定的借鉴意义。
When Wenchuan earthquake occurred,the vibration velocity generated by the seismic was monitored at Xiangjiaba Hydropower Station construction site.Through analyzing the actual waveform of vibration of huge earthquake,the changes of frequency of vibration,peak vibration velocity,vibration acceleration and displacement were obtained,and all of those have a certain reference for researching controlling standard of blasting vibration.
