摘要：

The key factors involved in the train derailment on bridges or lines have been discussed in this paper. Also the statistics of derailment accidents with an upward trend occurred in recent years, all over the world, are listed. Analysis of the reasons for train derailment, geometric criterion and mechanical mechanism of train derailment are discussed. Then the authors make an analysis of difference of train derailment between bridges and lines from five aspects. The conclusions have been drawn from the comparative analysis of train derailment involved in lateral stiffness, derailment time history, flow field, motion equation and resonance. There is no characteristic of time history for a certain distance on line derailment. And the mechanical characteristics of vehicle-bridge system are more complicated than the vehicle-line system under wind loads.
