摘要
本文利用复变函数方法求解SH波对各向异性凹陷地形的散射问题。文中给出构造求解稳态SH波入射时该问题题答的函数逼近序列和边界条件的表达式。利用Hermite函数和它的正交性,文中将待解的问题归结为对一组无穷代数方程组的求解。最后,计算了具有半圆形凹陷的各向异性地形对SH波的散射。研究结果表明,各向异性对地表运动的影响是明显的。
A new approach, based on complex function to solve the SH-wave scatteting by a canyon tapography inan anisotropic medium is introduced in this paper. This paper gives the complete function Series and general expressions for boundary condition to approach the solution of steady state scattering of SH-wave on a canyon topography inan anisotropic medium. The problem to be solved can be summarized as the solution of infinite algebraic equation series by using Hermite function. Finally, computational results of scattering of plane SH-wave by a semi-cylindrical canyon topography are presented.
