现今已可产生并观测横波,不过没有像纵波那样的方便和技术标准,而且在地震记录上可以用不同的方法识别它们。横波的潜力在低速(对于相同频率——相当于较短波长和较高分辨率)方面并不十分大,但在探测地壳的应力和应变方面,横波的潜力却不同于纵波。因此为了发挥横波信息的潜力,就需要综合使用ρ波和S波。综合使用不同波型的复杂情况,应当认为是获得附加信息的机会。典型的实例是根据ρ波和SH波反射分别估算同一界面深度的观测,其结果可能大不相同。这种差异是由于微小层状介质的各向异性所造成。在有利情况下,描述这种各向异性的某些参数可由不同的估算深度和偏移距平方一时间平方表示不同反射的曲率推导出来,因为在各向异性介质中,垂直极化横波与水平极化横波明显地不同,所以三种波综合观测,展现了更多的前景。
S-waves can now be produced and observed, but without convenience and technical standards like longitudinal waves, they can be identified in different ways on seismic records. The potential of shear waves is not so great at low speeds (for the same frequency - the equivalent of shorter wavelengths and higher resolutions), but the potential of shear waves is different from that of longitudinal waves in detecting crustal stress and strain. Therefore, in order to exert the potential of transverse wave information, it is necessary to comprehensively use ρ wave and S wave. The complex use of different wave patterns in combination should be considered as an opportunity to obtain additional information. A typical example is the estimation of the depth of the same interface based on the reflection of the ρ wave and the SH wave respectively. The results may vary widely. This difference is due to the anisotropy of the tiny layered media. In favorable cases, some of the parameters describing this anisotropy can be deduced from different estimated depths and offsets squared-time-squared representing the reflections of different reflections because in anisotropic media the vertical polarization is proportional to the horizontal Polarized shear waves are significantly different, so the three waves comprehensive observation, showing more prospects.
