結果表明：垂直入射時，小深寬比軟夾塞上方地表位移幅值有較大的放大，小深厚比軟夾層的地表位移幅值也有一定的放大，且後者為前者的下限；波接近掠入射時，軟夾塞正上方地表點和軟夾層的中國地震局工程力學研究所碩士學位論文一地表位移幅值都沒有放大，而軟夾塞迎波面一側地表點的位移幅值會有一定的放大；軟夾塞上方的地表位移運動有較強烈的扭轉效應，且此扭轉效應隨入射波頻率的增高而增強。It shows that hard layers barely affect the ground motion and can thus be neglected in general. the soft layers, on the other hand, can influence the ground motion greatly, i. e., seismic response will decreases when the period less than 0. 1s and it increases when period greater than 0. 3s, but it will not change significantly for the long period over 3s. therefore the whole effect of the soft layers on earthquake ground motion in fact depends on the characteristic frequencies input
研究結果表明，硬夾層的影響很小，一般情況下，可以不予以考慮；軟夾層有較顯著的影響，其影響主要表現為：對周期小於0 . 1s的高頻段反應減小，對周期大於0 . 3s的較長周期段反應增大，而對周期長達3s及以上周期段反應幾乎無影響，因此，軟夾層對場地地震反應影響的總體作用是增大還是減小反應，取決于計算基底輸入地震動的頻譜特性。Unique hydrogeology feature of soft soil two - layer structure in wuhan city determines particularity of decreasing confined water in deep excavation
