高分辨率浅层地震方法是在近地表调查中使用最为广泛的方法。然而,在许多情况下,地震资料的解释经常会出现错误。在本文中,我们介绍了三个例子,分析了造成P波,SH波,多道的面波(MASW)地震资料解释的错误原因,大都是由于在表面或地下条件约束不确当引起的。第一个例子是P波反射剖面上的一个波的特征被解释为浅层断裂带,但后来证实它是由高水平的背景噪音引起的,因为采集测线通过了一个公路交叉口。第二个例子是SH波反射地震剖面上一个波特征被解释为是逆倾向滑断层,但有针对性的钻探表明,它是一个侵入到基岩面的一个深层局部侵蚀。最后,第三个例子,MASW调查剖面上,一个陡倾特征一开始被解释为基岩谷。然而,后来的钻探表明这是一个非常软的湖泊沉积物,后者严重损坏了应用面波频段。虽然最初的解释是不正确的,但这刺激地球物理学家和地质学家之间的讨论,并强调地球物理数据采集的时候,采集之前以及采集之后需要科学家之间有意义的合作与讨论。
High-resolution shallow seismic methods are the most widely used method in near-surface surveys. However, in many cases, interpretation of seismic data often leads to errors. In this paper, we introduce three examples and analyze the causes of the errors that cause the interpretation of P-wave, SH-wave, multichannel surface wave (MASW) seismic data, mostly due to improper surface or subsurface constraints. The first example is the characteristic of a wave on a P-wave reflection profile interpreted as a shallow fault, but later it was confirmed that it was caused by a high level of background noise because the acquisition line passed a road intersection. The second example is that a wave feature on the SH wave reflection seismic profile is interpreted as a reverse dip-slip, but targeted drilling indicates that it is a deep localized erosion that intrudes into the bedrock surface. Finally, in the third example, a steep dip in the MASW profile was originally interpreted as bedrock. However, subsequent drilling showed that it was a very soft lake deposit, which severely damaged the application of surface wave frequency bands. Although the initial interpretation was incorrect, it stimulated discussions between geophysicists and geologists and emphasized the need for meaningful cooperation and discussion among scientists when, when and after geophysical data collection.
