摘　　要：应用加权残值法,讨论了峡谷形状对平面SH波的散射影响。结果表明:峡谷的宽深比a/b及其断面的形状对SH波的散射有明显的影响。而且频率的变化对地面放大作用影响显著。By using the method of weighted residual, the effects of canyon shape on scattering of plane SH wave was studied in this paper. It is concluded that evident effects of differen width depth patios and shapes of canyon on SH wave scattering could be observed, and the influence of round amplification due to frequency are more significant.

关 键 词：加值残值法 SH波 散射 河谷形状
