| 摘 要： | 随着地铁轻轨的迅速发展，我国大多数地电阻率测项受到不同程度干扰，诸多学者为此提出采用小波方法进行滤波的建议。文中拟采用小波和HHT滤波方法，以受津滨轻轨干扰严重的塘沽地电阻率观测资料为例，进行降噪处理，对比2种方法的滤波效果，以获得更好的滤波方法。

| Abstract: | With the rapid development of subway in China, most of the geo-resistivity observations have been affected in different degree. Many scholars proposed de-noising research using wavelet method. Here, we take geo-resistivity observation of Tanggu Seismic Station for example, which is seriously disturbed by Binhai Mass Transit, using the wavelet and HHT filtering methods respectively. By comparing the filtering effects of the two methods, we get the better method for the de-noising process of geo-resistivity observation disturbed by subway. |
