圆弧形层状沉积谷地对入射平面P波的散射解析解

摘要

利用Fourier-Bessel级数展开法，给出了圆弧形层状沉积谷地对入射平面P波散射的一个解析解，并利用该解分析了谷中层状沉积排列顺序及相对刚度等因素对入射波散射的影响．%An analytical solution of scattering of plane P waves by circular-arc layered aluvial valleys was derived by Fourier-Bessel series expansion technique, and the solution was utilized to analyze the effects of alluvial sequence and their relative stiffness on the scattering of incident waves.
