Abstract
Combining with a new theory of region segmentation, the wave field of SH wave in trapezoidal convex terrain with circular holes is obtained by complex variable function method. By solving the boundary conditions, the surface displacement amplitude expression of the model is obtained. Numerical calculations show that the incident wave angle, wave number and hole radius have a significant influence on the trapezoidal convex topography.
