主 题：Rayleigh wave regression Q_βstructure
摘 要：Based on Rayleigh wave recorded in a 55 m long profile, dispersions of phase and group velocities in 5-40 Hi areobtained by multi-channel recording and processing method. Further, the velocity structures of shear waves in thesoil above 35 m are obtained by inversions of velocity dispersions. Meanwhile, the spatial distribution of amplitude spectra of fundamental mode of Rayleigh waves is calculated, the dispersion curves of attenuation coefficientSby using linear regression method are also given, and finally, the structures of oP in each soil layer are obtained byinversion. The results show that Qβ 10 in soft deposit layer and Qβ is about 30 in weathering bedrock
