Abstract

Both frozen soil and liquefaction have a great influence on the dynamic response of pile foundation. Based on the OpenSees platform, a calculation model of pile-soil interaction was established. The peak ground motion of 0.6g was input and the acceleration, displacement, pore water pressure and effective stress of pile foundation and soil were analyzed. The results show that liquefaction occurs at the bottom of the sandy soil and the excess pore pressure ratio exceeds 0.8. The coverage of the frozen soil layer causes the pile foundation not to produce greater lateral displacement when the bottom soil layer is liquefied, which improves the bearing capacity of the pile foundation.
