| 摘 要： | 根据弹性长枕的结构特点及受力特性，运用有限单元法建立弹性长枕无砟轨道垂向受力有限元计算模型。通过分析不同长度弹性轨枕在不同支撑长度下的轨下及枕中弯矩情况，确定了弹性长枕式无砟轨道枕长与支撑长度的合理比例约为04。

| Abstract: | According to the structural characteristics and stress characteristics of long elastic sleeper,finite element calculation model is established for vertical stress of long elastic sleeper ballastless track using finite element method.Through comparison of bottom and central flexural moment of different elastic sleepers under different supporting length,the reasonable ratio of sleeper length and supporting length of long elastic sleeper ballastless track is about 0.4. |
