摘要:
利用永安井秒采样水位仪记录到的地震波形数据,与CMG-3ESPC-60地震计比较,对井水位同震响应特征、响应能力、地震波加载响应等方面进行分析。结果表明:秒采样水位仪也可记录到地震体波(P波、S波)和面波R,面波频散现象清晰,较好反映地震波作用过程及震源破裂过程中能量的释放;井水位对近场地震和远场地震响应程度存在差异,其同震响应能力与震级、震中距无必然联系;同CMG-3ESPC-60地震计相比,二者都存在明显周期信号,面波频段波幅变化最大,为主要中心频率,与CMG-3ESPC-60地震计速度值积分振幅谱谱形态一致,也具有较宽频带,但低于CMG-3ESPC-60地震计。
Abstract:
Using the seismic waveform data recorded by the second sampling water level instrument of Yong'an well and compared with the CMG-3ESPC-60 seismometer,the coseismic response characteristics,response capability and seismic wave loading response of the well water level are analyzed. The results show that: The second sampling water level meter can also record the seismic body wave(P wave,S wave)and surface wave R,and the dispersion phenomenon of surface wave is clear,which can better reflect the action process of seismic wave and the release of energy in the process of source rupture; well water level has different responses to near-field earthquakes and far-field earthquakes, and its coseismic response capability was not necessarily related to magnitude and epicentral distance; compared with the CMG-3ESPC-60 seismometer,both of them have obvious periodic signals,and the amplitude of the surface wave band changes the most, which is the main center frequency. The water level waveform is consistent with the velocity value integral amplitude spectrum of the CMG-3ESPC-60 seismometer, and also has a wider frequency band,but lower than that of the CMG-3ESPC-60 seismometer.
