5 、复杂介质凸起地形对地展波传播的影响山体对地面运动有放大作用，在山脚则有抑制作用，山包之间峡谷的土层反应放大倍数受山包之间距离的影响较大。 |
| 10. | The unsaturated soil ( sr = 98 % ) make the topography effect more noticeable than that of saturated soil and one - phase soil : in the amplification area the amplification factor is bigger than that of saturated soil and one - pahse soil , while in the constraint area the amplification factor is smaller than that of saturated soil and one - phase soil
介质的种类对地形放大倍数有比较明显的影响。欠饱和土比单相土具有更明显的地形效应，在被抑制区欠饱和土的位移或加速度放大倍数比单相土更小，在放大区位移或加速度的放大倍数比单相土更大。 |
