随着铁路运量的日益增长,列车速度的不断提高与轴重的加大,对轨道的技术状态提出了越来越严格的要求。为保持轨道技术状态良好,及时有效地发现轨道上存在的问题是十分必要的。因此,当前许多国家都在积极研究轨道检测手段,引用新技术,改进检测方法;检测内容不断扩大和深入。轨道检测技术已经逐渐形成了一个专门的技术领域,成为现代化铁路的一个不可缺少的组成部分。
With the increasing railway traffic, the continuous increase of train speed and the increase of axle load have put more and more strict requirements on the technical status of the track. In order to keep track technology in good condition, it is very necessary to find out the problems in orbit in time and effectively. Therefore, many countries are actively studying orbital detection methods, citing new technologies, improving detection methods; detection content continues to expand and deepen. Track detection technology has gradually formed a specialized technical area, becoming an indispensable part of modern railways.
