利用波函数展开法给出了含多个圆弧状沉积层河谷(盆地)场地对平面SH波二维散射问题的一个解析解,并以具有三个沉积层的河谷为例,分析了河谷中沉积层层数与排列次序对SH波散射的影响。
Using the wave function expansion method,the analytical solution to the two-dimensional scattering problem of valley(basin),which contains multiple circular-arc alluvial layers,in the case of plane SH waves incidence,is obtained.With a valley containing three alluvial layers as an example,the influences of the number of alluvial layers and their sequence on the scattering and diffraction of SH waves are analyzed.
