ABSTRACT
This paper presents an analytical solution to the ground motion of an isosceles hill with slope change under incident SH waves. A new partitioning method, multi-region-matching technique (MRMT), is proposed in this paper to establish an accurate analytical solution model. Based on the complex function method and multipolar coordinate transformation, the infinite algebraic equations are established according to the continuity conditions at the two auxiliary boundaries. Fourier series expansion method in complex-domain is adopted to solve the unknown coefficients in wave field expressions. Numerical results demonstrate the slope of the hill is an important parameter affecting the anti-plane response.
