| 摘 要： | 位于京沪线上的南京长江大桥系该线贯通大江南北的主要咽喉.由于其轨道结构的差异,相应的轨道几何状态变化是不一样的.本文采用不平顺幅值和功率谱相对比的方法,综合分析大桥在重载快速行车条件下的轨道几何状态变化规律,为合理制定相应的养修标准提供了技术支持. |
| 关 键 词： | 轨道几何不平顺 功率谱 变化规律 |

| Abstract: | The Nanjing Changjiang River bridge which is located in Beijing-Shanghai line is the key route way that crosses the river from south to north.Owing to the differences in its rail structure,the change of track geometry is different.This paper contrasts the means of amplitude value with the means of power spectrum,and studies the bridge's change rule in track geometry status synthetically,it can provide tech support for establishing repair and maintain standard reasonably. |
| Keywords: | track geometry irregularities power spectrum change rule |
