Abstract: In view of existing questions in the aseismic design of high-speed railway bridge pile foundation under strong earthquakes, the aseismic performance of pile foundation based on a multilevel fortification goal is proposed and the corresponding evaluation index and rational values obtained. This paper presents two kinds of calculation model, a Static Pushover analysis model and a SR dynamic model. Firstly, the structure capacity curve, the performance control value and constitutive relation to translational springs, and the rotational springs at the bottom of the pile cap can be obtained by the Static Pushover analysis model. Secondly, structure response value can be attained by the nonlinear time history analysis using the SR dynamic model. The aseismic performance of pile foundation is evaluated by the comparison of control points on the capacity curve. With one pier of a 32m simply-supported box girder bridge in high-speed railway as the research subject, the feasibility of the method is verified by case study.
