本文主要对横波应用中最难解决的三个问题,即横波的静校正;横波的地表效应;横波的方位各向异性效应的特点,表现形式和复杂性等作了陈述。结合宽角爆炸地震测深方法的实际情况,讨论了横波的传播、偏振、振幅、走时和速度等特性。说明了应用横渡探测地壳、上地幔结构的利弊。横波效应在纵波应用中也许并不存在或可忽略的现象,在横波应用中却不可忽视。也是横波应用有别于纵波的原因。如何根据横波效应的特性来发展横渡的处理和显示技术,是今后研究和发展横波应用的关键。
In this paper, three problems that are the most difficult to solve in the application of transverse waves are mainly described: the static correction of transverse waves; the surface effects of transverse waves; the characteristics, manifestations and complexities of the azimuthal anisotropy of transverse waves. Combined with the actual situation of sounding method for wide-angle blasting, the characteristics of shear wave propagation, polarization, amplitude, travel time and velocity are discussed. Describes the pros and cons of using cross-detection of the crust and upper mantle structures. The effect of transverse waves may not exist or can be neglected in the application of longitudinal waves, which can not be neglected in the application of transverse waves. It is also the reason why transverse waves are different from longitudinal waves. How to develop the cross-processing and display technology according to the characteristics of the S-wave effect is the key to the future research and development of the application of the S-wave.
