由非均匀平面纵波与非均匀横波沿自由界面传播时相互迭加形成的瑞雷面波，具有能量强、衰减慢、波速低的特点。根据瑞雷波的频散特性开发的瑞雷波勘探方法，能够弥补常规地震勘探浅层盲区的不足，且具有更高的勘探分辨率，尤其适合浅层的工程勘探及煤矿井下独头巷道的超前探测。
The Rayleigh surface waves formed by the superposition of non-uniform longitudinal and non-uniform transverse waves propagating along the free interface have the characteristics of strong energy, slow attenuation and low wave velocity. The Rayleigh wave exploration method developed based on the Rayleigh dispersion characteristics can make up for the lack of shallow blind spots in conventional seismic exploration and has higher exploration resolution and is especially suitable for shallow engineering exploration and single-lane underground coal mine tunnel Advanced detection.
