- Abstract
In seasonal permafrost regions, the freezing and thawing of seasonally active layers can significantly change the site ground vibration characteristics and thus have a great impact on the seismic response of buildings. In this study, a three-dimensional finite element model of pile foundation is established considering the seasonal frozen soil field effect, and the influence of seasonal frozen soil layer on the seismic response of pile foundation is analyzed. The results show that the seasonal frozen soil layer greatly inhibits the elevation amplification effect of the surface acceleration amplification factor. At the same time, the strong constraint of the frozen soil layer makes the relative motion of pile foundation and shallow-buried foundation smaller, and the peak acceleration amplification factor of the two is less different. In this case, the existence of seasonal frozen soil layer is beneficial to pile foundation.
