【摘要】 本文通过波函数展开法给出了半球形峡谷在平面P波入射下的地表位移,半空间表面的各点包括峡谷的边缘点的位移幅值没有表现出很高的位移放大作用,最大的幅值没有超过4,并且靠近半球形峡谷的左半部分地形呈上升趋势,而在靠近右半部分地形呈下降趋势。更多还原

【Abstract】 In this paper, the ground motion of the hemispherical canyon and some conclusions under incident P wave was achieved by using series expansion. The displacement of every point on the ground is no more than 4. The left side of the hemispherical canyon show rising trend and the right side show falling trend.更多还原
