本文通过北京房山周口店台维开克型地震仪的两个深源远震记录波形实例,阐明了借助综合地震图的计算来研究该台站下方介质结构的方法。 文中给出14个典型模型的综合地震图与观测波形的对比分析。结果表明,应用本文提供的方法,对介质模型的可接受程度,可由理论波形与观测波形的可相比拟程度进行判断。文中据此给出了该台站下方的介质结构模型。
In this paper, two deep-source teleseismic waveforms recorded by the Taiwanese-speaking Kekeke Seismograph in Fangkoudian, Beijing were used to illustrate the method of studying the structure of the medium beneath the station by means of comprehensive seismogram calculation. In this paper, the comparative analysis of synthetic seismograms and observed waveforms of 14 typical models is given. The results show that using the method provided in this paper, the acceptable degree of the media model can be judged by the comparable degree between the theoretical waveform and the observed waveform. According to this, the media structure model below the station is given.
