横波地震勘探是一种抗干扰能力强、分辨率高的地震勘探方法,被广泛用于地质灾害调查、工程地质勘探、露天煤矿勘探等方面。由于横波衰减快,加之受激发方式制约,一般勘探深度均较浅,常被用于100米以上浅层地震勘探。浅层地震勘探需要查明的多为较小的地质体,对精度要求高,分辨率问题显得尤其重要。本文就横波勘探中影响分辨率的几个问题及如何提高横波勘探分辨率进行分析和探讨。
Sheung waves seismic exploration is a strong anti-jamming, high resolution seismic exploration methods, are widely used in geological disaster investigation, engineering geological exploration, open-pit coal exploration and so on. Due to the fast attenuation of transverse waves and the restricted mode of excitation, general exploration depths are shallow and are often used for shallow seismic surveys over 100 meters. Shallow seismic exploration needs to be identified more than the smaller geological body, high precision, resolution is particularly important. In this paper, several problems influencing resolution in transverse wave exploration and how to improve the resolution of transverse wave exploration are analyzed and discussed.
