摘要

地球自由振荡的研究已成为探测地球内部结构的重要手段之一。本文首次采用基于Hilbert Huang变换的边际谱方法，结合铜河站不剔除固相潮汐的钻孔应变资料，提取了汶川8.0级地震、智利8.8级地震和日本本州东海岸9.0级地震激发的球面自由振荡模态，结果与PREM模态非常接近。其中，汶川地震测试了24个球形基频模态，智利和日本地震均为76个，由0S0和0S2~0S76组成。由于这些强震模态存在分谱现象，边际谱法可以有效地提取大地自由振荡。

Using the Marginal Spectrum Method to Extract Spherical Free Oscillation of Strong Earthquakes

The research on earth free oscillation has become one of important methods to detect the internal structure of earth. This paper uses the marginal spectrum method based on Hilbert Huang transform for the first time, and the Tonghe station's borehole strain data without removing solid tide, then we extracted spherical free oscillation mode that are motivated by Wenchuan M8.0 earthquake, Chile M8.8 earthquake and the east coast of Honshu of Japan M9.0 earthquake, the results are very close to the PREM mode. Among which, the Wenchuan earthquake is tested 24 spherical fundamental frequency modes, the Chile and Japan earthquakes are both 76, which consist of 0S0 and 0S2~0S76. The marginal spectrum method can effectively extract the earth free oscillation because of these strong earthquakes' mode have spectrum divided phenomenon.
