- Abstract:
- Based on Biot's theory of fluid saturated medium,the Indirect Boundary Element Method(IBEM)is used to solve the scattering problem of the plane qP1 wave from transversely isotropic(TI)saturated alluvial valley in frequency domain.The correctness of the method is verified by comparing with the results of isotropic saturated sites.Numerical calculation and analysis of different situations were carried out,with emphasis on the influence of TI properties of alluvial valley on the dynamic response of the surface.The results show that the TI properties have significant influence on the amplitude and spatial distribution of surface displacement,and the degree of influence depends on the incident angle,incident frequency and observation point location of the qP1 wave.Considering the TI properties,the scattering of the plane qP1 waves by alluvial valleys can be simulated more accurately.
