摘要
瑞利面波是一类频率较低、能量较强的次生波 ,且主要沿着介质的分界面传播 ,其能量随着与界面距离的增加迅速衰减 ,它与反射波、折射波一样都含有地下介质的地质信息。本文基于瑞利面波表层调查的基本方法 ,以多层、倾斜层的实际数据为实例进行表层结构计算 ,再次证明利用地震勘探单炮记录中的瑞利面波进行表层调查是可行性的。
Rayleigh wave is a secondary wave characterized by low frequency and strong energy,propagating mainly along the interface of medium and rapid attenuation of energy with increase in interface distance. Like the reflection and refraction,the Rayleigh wave also contains geologic information of subsurface medium.Based on basic methods investigating near-surface structure by Raileigh wave,the paper computes near-surface structure using real data of multi-layers and dip-layers,which proved again that it is feasibility using Rayleigh wave on seismic single shot records for investigation of near-surface structure.
