摘要：

Considering the randomness of earthquake and the nonlinearity of soil, introducing viscous-spring boundary and the orthogonal test method, the loading pattern of inputting acceleration directly in harmonic response analysis is proposed and the parametric sensitivity analyses of stochastic vibration response for pile-soil interaction system based on pseudo-excitation method, equivalent linearization method and definite dynamic finite element method are proposed. The parametric sensitivity analyses of pile-soil system with respect to pile-soil modulus ratio, earthquake design level, and pile slenderness ratio are conducted in detail. The results show that the pile-soil stiffness ratio is the most sensitive one among three factors.
