本文介绍了面波的特点,给出了几种消除面波的主要方法,并简略地讨论了各种方法的局限性。在此基础上提出一种新的消除面波的方法——基于干净道的匹配滤波法,详细地论述了这种方法的基本原理,并指出可能存在的问题。与其它方法相比,这种方法简便易行;利用这种方法处理实际资料,效果良好。

Starting with a short review on the features of the surface-wave this paper lists several method associated with their limitations in removing them. The discussion consequently leads to a new method on surface-wave removal- a method of matched filtering based on noise-free traces. The philossphy of the new method is detailed in the paper along with the potential prlblems in its implementation. Compared to other methods, this method appcsrs to be simple and feasible. The efficiency of the method is demonstrated with a real data example.
