  11. 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。
