Study on Dynamic Response of Bridge Pile Foundation at the Permafrost Regions under Seismic Load
In order to decrease influences of increase in air temperature and engineering disturbance on the permafrost underground, dry bridge, also named as bridge instead of embankment, is adopted along the Qinghai-Tibet Railroad according to different earth temperature and ice content at permafrost regions. Shaking table tests for scale model of pile foundation were executed and the characteristics of seismic response of the piles were analyzed. On the basis of the tests, the characteristics of dynamic response of pile foundation of Qingshui River Bridge were analyzed by dynamic finite element analysis. It is of current significance for research on the quantitative effects of dynamic load on pile foundation deformation at permafrost regions and for safe operation of the Qinghai-Tibet Railroad.
