汶川大地震远区实测振动速度波形分析

Analysis of Vibration and Waveform Remotely Measured for Wenchuan Earthquake

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 ana/yzing 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.
