瑞利波勘探方法广泛应用在各种工程勘察领域中,其中快速准确的瑞利波频散成像方法是进行瑞利波勘探方法的关键因素之一。这里通过理论数据详细介绍了三种频散成像方法的实现过程,并深入分析了不同方法的频散成像效果,通过对比发现,F-K 变换法和τ-p 变换法虽可以清晰地看出瑞利波能量的分布特点,但并不利于频散曲线的提取,而相移法则具有更好的频散成像效果,可以得到更高频率和更高阶次的瑞利波频散曲线。

Rayleigh wave exploration method is used in various fields of engineering survey widely,and a fast and accurate Rayleigh wave dispersion imaging method is one of the key factors in Rayleigh wave method.This paper introduce three disper-sion imaging methods implementation in detail by synthetic data,and analysis the dispersion imaging results of different ima-ging methods,by comparison,we can clearly see the Rayleigh wave distribution of energy in the imaging results of F-K trans-form method andτ-p transform method,but it is not conducive to the dispersion curve extraction,and the phase shift method has better dispersion imaging results,and can get a higher frequency and higher order Rayleigh wave dispersion curves.
