In the Code for Rating Existing Railway Bridges of China, the control index of lateral stiffness of piers is lateral maximum amplitude of pier top, but the influencing factors are not considered completely. This paper presents the statistic analysis for dynamic characters of railway solid piers, and the integrated index which is most sensitive to the lateral maximum amplitude of pier top, the lateral vibration rule of railway solid piers is researched both practically and theoretically and the experimental and calculated value are compared with the limited value in rating code. It is concluded that the limited value, which is only associated with piers' dimension, can not reflect the characteristic of couple vibration between the beams and piers, and the limited lateral amplitude should be associated with the structural characteristic of beam-pier system.
