铁路运输面临着更高的需求，这就需要使用速度更快、轴重更重的列车。这些都增加了轨道几何退化的速度，这就需要对几何退化进行更有效的控制。将轨道几何形状保持在可接受的水平需要适当的检查和维护计划，这不可避免地需要深入了解轨道几何形状退化。此外，还需要确定退化建模的最有效方法。要做到这一点，至关重要的是将公布的结果综合成一个摘要，总结哪些是已知和验证的，哪些是不是重要的一步。为此，本文回顾了轨道退化模型，讨论了各种退化措施，并提出了未来研究的方向。研究发现，将力学方法和统计学方法相结合，可以更准确地预测轨道几何退化行为。
Railway transportation is exposed to a higher demand that necessitates the use of trains with higher speed and heavier axle loads. These increase the track geometry degradation rate, which needs a more effective control on geometry degradation. Keeping the track geometry in acceptable levels requires proper inspection and maintenance planning that inevitably entails in-depth knowledge of track geometry degradation. In addition, it is needed to identify the most effective approach for degradation modelling. To do so, it is vital to synthesis published results into a summary of what is known and validated and what is not as a major step. To this end, this paper reviews track degradation models, discusses various degradation measures, and proposes directions for future researches. It is found that combining the mechanistic and statistical approaches can leads to a more accurate prediction of track geometry degradation behaviour.
