| Abstract: | Using the wave function expansion method,the analytical solution to the two-dimensional scattering problem of valley(basin),which contains multiple circular-arc alluvial layers,in the case of plane SH waves incidence,is obtained.With a valley containing three alluvial layers as an example,the influences of the number of alluvial layers and their sequence on the scattering and diffraction of SH waves are analyzed. |
| Keywords: | plane SH waves scattering multiple alluvial layers valley(basin) analytical solution |
