各向异性介质中有衬砌的非圆形结构与SH波的相互作用

本文利用复变函数方法求解各向异性介质中有衬砌的非圆形结构与ＳＨ波的相互作用问题．各向异性介质可以用来模拟结构周围的地质条件．利用作者在文献［５，７］中的方法决定介质和衬砌结构中的散射波，结合Ｓａｖｉｎ在文献［６］中求解有衬砌结构所采用的对结构轮廓线进行近似处理的方法，并利用结构与介质的连续性条件与衬砌内边界上的边界条件，对问题进行求解．作为算例．本文讨论了在同一种各向异性介质中，两种不同材料组成的正方形有衬砌的结构与ＳＨ波的相互作用问题．给出了数值分析结果．

The Interaction of Plane SH-Waves and Non-Circular Cavity Surfaced with Lining in Anisotropic Media

This is an expand of the complex function method in solving the problem of interaction of plane SH-waves and non-circular cavity surfaced with lining in anisotropic media.We use the method similar to that incorporated in Ref.2]added with Savin's method for solving stress concentration of non-circular cavity surfaced with lining in clasticity.Anisotropic media can be used to simulate the conditions of the geology. The solving proceeding for this problem can be processed conveniently in the manner similar to that introduced in Ref.2].In this paper,as illustrated in the example,numerical studies have been done for a square cavity surfaced with lining in anisotropic media.
