## Series solution for Scattering of Plane SH-Waves by Multiple Shallow Circular-Arc Canyons

• 摘要: 本文采用解析法研究相邻多个线圆弧凹陷地形对平面SH波散射问题。文中由分离变量法把相邻多个圆弧凹陷对平面SH波的多重散射表示为各局部坐标中的级数之和,再利用Graf加法公式的内域和外域表达式进一步表示某个局部坐标中的双重无穷级数形式。问题最后可归结为求解一组无穷型的线性代数方程。文末给出了相邻两个等直径浅圆弧凹陷地形的多种深宽比对地面运动的影响的计算结果,并讨论了浅圆凹陷地形对波的屏蔽及它们之间的相互作用。
