Method of neighboring trace transient Rayleigh wave and its application in compactness inspection

 Based on previous research results,the theory of extracting transient Rayleigh surface wave using τ–p transform of neighboring trace calculated dispersion curve is described,and the empirical mathematical model considering compactness and velocity of s-wave,and depth is established.The calculation of theoretical model and the results of comparative inspection show that: 1) τ–p transform can pick up the transient Rayleigh surface wave effectively and correctly,and the separated Rayleigh wave meets the need o...
