圆弧形沉积河谷场地在平面P波入射下的响应

Response of circular－arc alluvial valleys under incident plane P waves

利用Fourier－Bessel级数展开法，在频域内给出了圆弧形沉积河谷场地在平面P波入射下动力响应的一个解析解，并分析了入射波波长、入射角度与河谷宽度、深度等因素对动力响应的影响。

An analytical solution was derived for dynamic response of circular-arc alluvial valley under incident plane P waves by Fourier-Bessel series expansion technique. The effects of wavelength and angle of incident waves, and width and depth of alluvial valleys on the dynamic response were discussed.
