| 摘 要： | 文章利用“契合”思想,给出了地下弹性夹杂与地面上的等腰三角形凸起地形引起的SH波散射问题的解析解答。利用复平面下坐标移动,通过区域Ⅰ和区域Ⅱ以及区域Ⅱ和区域Ⅲ的“公共边界”位移应力连续条件,建立起求解该问题的无穷代数方程组并截断有限项进行求解,最后通过具体算例及结果分析得出相应结论。

| Abstract: | In this paper,the scattering of SH waves by an isosceles triangular hill above a subsurface elastic cylindrical inclusion is studied based on 'conjunction'.By using the moving coordinate method in complex plane,the conditions of displacement continuity and stress equilibrium at the interfaces of the two boundaries are set.The results are obtained by constructing a set of infinite linear algebraic equations.Finally,some conclusions are drawn by discussing the numerical results. |
