On the contrary, the degree of saturation plays an important role on p - wave propagation, if incidence is 90 degree. the amplification factor on surface related to the response of bedrock is the biggest if the media is one - phase media, and the factor is the smallest if the media is unsaturated media ( sr > = 90 % )
P波從底邊界垂直入射時，飽和度對地表土層的反應有顯著的影響。就地表土層位移和加速度相對于基巖的放大倍數來說，一般有這樣的規律：單相土的放大倍數最大，欠飽和土的放大倍數最小，飽和土的放大倍數居中。 -
Results show that the overlying soil with a soft interlayer can obstruct the rupture failure from bedrock up to the earth ' s surface, however, a soft interlayer which is deeply buried, will bring about a wider range of the earth ' s surface rupture failure ; in addition, the thickness of the soft interlayer may have effects on the rupture course of the overlying soil
從模擬的結果看出，軟夾層對上覆土層破裂有一定的阻礙作用；當軟弱層埋置較深時，一旦上覆土層破裂，失效土體的范圍較大；軟弱夾層的厚薄對上覆土層的破裂進程和破裂范圍也有影響。 -
A bearing surface transmits the interaction between an arch dam and its foundation, the strength of which directly affects the constraint of the bedrock to the dam, and thus affects the stress and deformation of the dam. the influence is studied in this paper with nonlinear finite element method, as an example, for a high arch dam in design. the results show that the influence on stress is only limited within the local area near the bearing surface, larger on the maximum principal tensile stress than on the principal compression stress, and the decrease of the strength does not cause unlimited increase of the maximum stress. the influence on the displacement of the top of the dam is smaller than that of the bottom of the dam, especially the relative downstream displacement. at the lower strength of the bearing surface, the relative downstream displacement at the bottom of the dam increases with the decrease of the strength
建基面是傳遞拱壩和基巖相互作用的紐帶，它的強度直接影響基巖對壩體的約束，從而影響壩體的應力和變形.採用非線性有限單元法，以設計中的某高拱壩為例，分析建基面強度對壩體應力和變形的影響.結果表明建基面強度對壩體應力的影響僅限於建基面附近的局部范圍，對最大主拉應力的影響要大於對最大主壓應力的影響，建基面強度的降低不會無限地增大壩體的應力數值；建基面強度對壩頂位移的影響較小，但對壩底位移（尤其是順河向相對位移）的影響較大，當建基面強度較低時，壩底順河向相對位移隨建基面強度的降低而增大 -

2 ) fourier amplitude spectrum analysis : ( 1 ) the fourier amplitude spectra decrease with the increment of depth ; and the components of fourier spectrum become complex in near - surface. ( 2 ) the fourier amplitude decrease faster in shallow soil level, and smaller in deep soil level. ( 3 ) compared with the deepest bedrock fourier spectrum, spectral components of higher than 5 hz decrease with depth decrease
