摘要：
In a wide frequency domain, vibration mode of a soil-pile-structure system on vibration table is investigated by experiment and FEM analysis. Then the influence of soft soil on the dynamic characteristics of upper structure is discussed. The dynamic characteristic of one order, which is corresponding to soft soil, is also pointed out when relative dynamic stiffness ratio of soil to upper structure is small enough.
