| 摘 要： | 本文研究了地球物理学家在重复地震（Doublet）研究方面取得的主要进展。针对天然重复地震数量少，区域分布有限，观测被动等问题，本文通过野外实验研究了人工震源信号的可重复性。由于人工震源位置已知，可随时主动激发，提出以此构建精确的人工重复地震，对于提高重复地震方法的可靠性与可行性具有重要意义，为进一步利用人工重复地震进行大尺度的地震探测奠定了基础。 |

| Abstract: | The development of doublet study is obtained. Doublets arise when two events display nearly identical seismograms at a common station, implying that events have similar focal mechanism and locations. Previous authors have identified and studied the signals from natural earthquake doublets. In allusion to the drawbacks of the low incidence rate and regional distribution of natural doublets and passive observation etc., the repeatability of artificial source is studied through field experiment. Further more, based on the known location and free excitation of the artificial source, accurate active doublet is put forward to construct. Its possible potential applications are also discussed. It makes great sense to improving the reliability and feasibility of doublet method and also lays a foundation for further large scale seismic exploration through active doublet method. |
